This micropower amplifier maintains uncompromised precision: maximum input offset voltage is 5μV at 25°C, maximum drift is 0.06μV/°C from –40°C to 125°C. Maximum input bias current is 15pA at 25°C, and 100pA from –40°C to 125°C.

These high precision input characteristics allow the use of large value feedback network resistors, keeping power consumption low without compromising accuracy, even at elevated temperature.

MILPITAS, CA & NORWOOD, MA – July 10, 2017 – Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC2063 zero-drift op amp which draws just 1.3μA typ (2μA max) on a 1.8V supply. This micropower amplifier maintains uncompromised precision: maximum input offset voltage is 5μV at 25°C, maximum drift is 0.06μV/°C from –40°C to 125°C. Maximum input bias current is 15pA at 25°C, and 100pA from –40°C to 125°C. These high precision input characteristics allow the use of large value feedback network resistors, keeping power consumption low without compromising accuracy, even at elevated temperature.

Rail-to-rail inputs and outputs simplify single supply use and enhance dynamic range. An integrated EMI filter provides 114dB electromagnetic interference rejection at 1.8GHz. With low 1/f noise inherent to its zero-drift architecture the LTC2063 is well suited for amplifying and conditioning low frequency sensor signals in high temperature industrial and automotive systems as well as portable and wireless sensor network applications.

The LTC2063 is available in SOT-23 and SC70 packages. The SC70 version includes a shutdown mode which reduces current consumption to just 90nA when the amplifier is not in use. This enables ultralow power duty cycled sensor applications. For example, a precision low duty cycle oxygen sensor circuit shown in the data sheet consumes less than 200nA average current.

“The LTC2063 enables a whole new class of precision measurement solutions which can be placed anywhere,” stated Ross Yu, Dust Networks^® marketing manager. “Its ultralow power and high precision are a perfect companion for Dust Networks’ SmartMesh^® wireless sensor networks, expanding the reach of precision measurements to places previously not practical.”

An example is the DC2369A wireless current sense reference board which uses the LTC2063 and LTP™5901-IPM SmartMesh IP™ module and other micropower components to create an isolated floating current sense measurement platform which operates for years on small batteries.

The LTC2063 operates on supply voltages from 1.7V to 5.25V and is fully specified from –40C to 125C. Pricing starts at $1.50 each in 1,000-piece quantities. For more information, visit www.linear.com/product/LTC2063.

Background

With the increased adoption of “Smart Factory” and Wireless Sensor Network technologies, sensors are expected to go anywhere and everywhere, operating over wide temperature ranges and consuming very little power. The circuitry surrounding the sensor in such systems needs to be very precise, especially at DC and low frequencies.  Zero-drift amplifiers have long been favored as sensor buffers and amplifiers for their low input offset voltage, low offset drift over temperature, and low 1/f voltage noise. In some cases the current consumption of these devices limits system battery life.

 

 

Industry’s Lowest Power Zero-Drift Op Amp

The new LTC2063 achieves outstanding zero-drift performance with 5μV max input offset voltage, 0.06μV/°C max drift from -40°C to 125°C, and 4.8μVp-p DC to 10Hz integrated voltage noise. Yet the LTC2063 consumes just 1.3μA current, which is better than 5x lower than the next nearest competitive part.

 

In addition to being the industry’s lowest power zero-drift op amp at 1.3μA on a 1.8V supply, the LTC2063 has a maximum input bias current of 20pA at 25°C, and 100pA max over the full temperature range. This allows the LTC2063 to directly interface with high impedance sensors, and also enables the use of higher value feedback resistors in the feedback network saving additional system power.  While some amplifiers exhibit a large startup current that far exceeds average power consumption, the LTC2063 maintains low current draw even during startup. It is available in tiny SOT-23 and SC70 packages. The 6-lead SC70 version includes a 90nA shutdown capability allowing for further power savings in duty-cycled applications. As an example, the LTC2063 data sheet shows a duty cycled oxygen sensor application which consumes less than 400nW.

 

With its ultralow quiescent current and outstanding precision, the LTC2063 is well suited for amplifying and conditioning low frequency sensor signals in high temperature industrial and automotive systems as well as medical, portable, energy harvesting and wireless sensor network applications.

MILPITAS, CA - December 12, 2016 - Linear Technology Corporation introduces the LTM2887, a 6-channel SPI/Digital or I²C μModule^® isolator with dual rail regulated power that targets low voltage components, including newer DSPs and microprocessors. Two well-regulated adjustable supply rails (up to 5V) deliver more than 100mA of load current over the isolation barrier, with up to 62% efficiency. The voltages may be adjusted as low as 0.6V for the auxiliary supply, while the isolated logic supply may be as low as 1.8V for SPI interfaces. Each supply provides a precise current limit adjustment pin and the ability to adjust the voltage using external resistors.

In industrial system applications, ground potentials can vary widely, often exceeding the tolerable range, interrupting communications or even destroying components. The LTM2887 breaks ground loops by electrically isolating the logic level interface on each side of an internal isolation barrier. This inductively coupled barrier withstands very large ground differential voltages up to 2,500VRMS.

A low EMI isolated DC/DC converter powers the LTM2887 and provides the isolated power to the communications interface and output rails. A separate logic supply pin provides direct interfacing with low voltage microcontrollers down to 1.62V, and an ON pin enables the LTM2887 to be shutdown and use less than 10μA. The LTM2887 provides uninterrupted communications for common mode transients greater than 30kV/μs and rugged ±10kV ESD (HBM) protection across the isolation barrier.

The LTM2887 is available in two communications interface versions. The LTM2887-I is I²C compliant at up to 400kHz with bidirectional serial data (SDA) plus clock (SCL) and three additional isolated CMOS logic signals that operate at up to 10MHz. The LTM2887-S is SPI-compliant and offers a total of six CMOS digital isolator communication channels. All channels operate at up to 10MHz and include three forward direction signals (CS, SCK and SDI) and three reverse direction signals (SDO, DO1 and DO2). When configured for SPI communications, the maximum clock rate is 8MHz for unidirectional communication or 4MHz for round-trip bidirectional operation.

The LTM2887 is available in 3.3V or 5V supply voltage versions and is offered in a 15mm x 11.25mm surface mount BGA package; all integrated circuits and passive components are housed in this RoHS-compliant μModule package. The LTM2887 is available in commercial, industrial and automotive versions, supporting operating temperature ranges from 0°C to 70°C, –40°C to 85°C and –40°C to 105°C respectively.

MILPITAS, CA - November 3, 2016 - Linear Technology announces the LT6658, a precision voltage reference that incorporates two high current output buffers. Based on a 2.5V bandgap voltage reference, each output can be separately configured for any voltage between 2.5V and 6V. Both outputs offer 0.05% initial accuracy, 10ppm/°C temperature drift and only 1.5ppm of low frequency noise. The outputs can drive up to 50mA and 150mA, respectively, and sink up to 20mA. Typical load regulation is only 0.1ppm/mA with up to 150mA of load current. In parallel, the buffer outputs can be combined for even higher current capability.

The LT6658 is ideal for driving the reference input for a high resolution ADC or DAC using one output, while simultaneously supplying power to other devices using the second output. Both outputs track each other over temperature and load, allowing them to address applications requiring ratiometric supply rails. The outputs have excellent supply rejection and are stable with up to 50μF over the entire specified operating range. With this output capability, the LT6658 can serve as both reference and regulator combined. Alternatively, the LT6658 can be used to generate a reference plus a virtual ground, or as two matched, tracking references.

“The increasing customer demand for precision voltage references with regulator-like drive has inspired us to create these ultra-buffered references,” says Brendan Whelan, Design Manager for Linear Technology. “The result is the groundbreaking LT6658 Refulator.”

The LT6658 is currently available in a 2.5V version. Options for 1.2V, 1.8V, 3V, 3.3V, and 5V will be available in the first half of 2017. Prices start at $2.35 each in 1,000-piece quantities. For more information, visit www.linear.com/product/LT6658.

MILPITAS, CA – November 3, 2016 – Linear Technology announces the LT6658, a precision voltage reference that incorporates two high current output buffers.  Based on a 2.5V bandgap voltage reference, each output can be separately configured for any voltage between 2.5V and 6V.  Both outputs offer 0.05% initial accuracy, 10ppm/°C temperature drift and only 1.5ppm of low frequency noise.  The outputs can drive up to 50mA and 150mA, respectively, and sink up to 20mA.  Typical load regulation is only 0.1ppm/mA with up to 150mA of load current.  In parallel, the buffer outputs can be combined for even higher current capability.

The LT6658 is ideal for driving the reference input for a high resolution ADC or DAC using one output, while simultaneously supplying power to other devices using the second output.  Both outputs track each other over temperature and load, allowing them to address applications requiring ratiometric supply rails.  The outputs have excellent supply rejection and are stable with up to 50μF over the entire specified operating range.  With this output capability, the LT6658 can serve as both reference and regulator combined. Alternatively, the LT6658 can be used to generate a reference plus a virtual ground, or as two matched, tracking references.

 “The increasing customer demand for precision voltage references with regulator-like drive has inspired us to create these ultra-buffered references,” says Brendan Whelan, Design Manager for Linear Technology. “The result is the groundbreaking LT6658 Refulator.”

The LT6658 is currently available in a 2.5V version. Options for 1.2V, 1.8V, 3V, 3.3V, and 5V will be available in the first half of 2017.  Prices start at $2.35 each in 1,000-piece quantities.  For more information, visit www.linear.com/product/LT6658.

A Voltage Reference with the Power of a Regulator

The LT6658 combines a performance voltage reference with 2 high-current output buffers.  The LT6658 offers the performance of a precision reference while being able to source up to 150mA and 50mA.  In parallel, the buffer outputs can be combined for 200mA of drive current.

The LT6658 is currently in production with a 2.5V version. Each output of this option can be separately configured for a voltage between 2.5V and 6V using 2 external resistors.  The complete LT6658 family will include versions with 1.2V, 1.8V, 3V, 3.3V, and 5V references to be available in the first half of 2017.  Prices start at $2.35 each in 1,000-piece quantities.

The LT6658 was designed to serve as both a reference and a regulator combined.  Both outputs have 0.05% initial accuracy, 10ppm/°C temperature drift and only 1.5ppm of low frequency noise.  The buffered outputs reduce the typical load regulation error to only 0.1ppm/mA with full load current.  The outputs have excellent supply rejection and are stable with up to 50μF over the entire specified operating range.  A typical application would be for the LT6658 to drive the reference input for a high resolution ADC or DAC using one output, while simultaneously supplying power to other devices using the second output.

What is Unique about the LT6658? 

Offers Very High Precision with High Current Capability

Allows the ability to drive multiple circuits with a single reference

Allows the ability to operate as a precision voltage regulator

Offers significantly better load regulation than most voltage references

Offers Excellent AC Performance

Offers significant improvement over an op amp buffer that can become unstable

Can drive large capacitive loads (such as ADCs) without ringing or instability

Includes Two Isolated Outputs with Separate Supply Pins

The channel-to-channel isolation ensures noise on one output does not affect other

Ensures outstanding Power Supply Rejection (PSRR)

Tracking

Includes Two Functions in a Single Package

Eliminates a regulator (includes supporting components, board space and routing)

Localizes the power distribution to a single IC and simplifies board layout

Offers cost savings

Without an LT6658, achieving LT6658-like performance requires the combination of a precision voltage reference with a dual buffer, or the combination of a voltage regulator with a precision reference.  Such discrete circuits have performance drawbacks, higher cost and a larger PCB footprint.  Since most amplifiers are not designed for precision reference-type applications, discrete buffers will often contribute significant errors such as line regulation.  Similarly, an LDO with a reference will exhibit combined errors such as offset and temperature drift.

High Fanout

The LT6658 “Refulator” is ideal for high fanout precision reference applications for ADCs and DACs.  With excellent AC performance, the LT6658 exhibits fast settling, even when used with SAR and delta-sigma ADCs, which commonly appear as a switched capacitive load.  The LT6658 avoids excessive ringing or instability which is typical in an op amp buffer, in the presence of switching transients.  For most voltage references, supplying appreciable current can generate significant errors. With only 0.1ppm/mA of load regulation and its ability to comfortably source 150mA and 50mA, variation in loads will not affect each other.

High Capacitive Loads

The LT6658 is designed to drive loads from 1uF to 50uF.  When driving a capacitor switching circuit, such as a SAR

or delta-sigma converter, it remains stable and settles quickly.  The buffered outputs ensure that capacitive glitching on one output will not affect the other output. Both LT6658 outputs are ideally suited to drive separate ADCs.

Regulator Applications

The LT6658 is ideal as a regulated power source for microcontrollers and precision analog circuits.  Whether the application requires very high precision power, which can be large and costly, or simply a low noise regulator, either output of the LT6658 can handle the job. With combined capability, the LT6658 can eliminate the need for a separate regulator, supporting components, board space and routing.

Tracking Applications

The LT6658 outputs track each other over temperature and load, making them suitable as ratiometric supply voltages.  This is valuable in difference amplifiers, bridge circuits and other sensor circuits.  If the 2 LT6658 outputs are used for separate ADCs, the tracking feature maintains consistent conversion results between both.

Isolation Applications

The LT6658 outputs are buffered separately and exhibit excellent channel-to-channel isolation, especially if they are powered separately.  Combined with their ability to supply

appreciable load current, corruption on one output will not affect the other.

Low Noise Applications

The LT6658 offers very low noise performance, which can be reduced even further using the noise reduction pin. By placing a capacitor on the NR pin, the noise bandwidth of the internal reference is limited; with no capacitor on the NR pin, the voltage noise density is around 150nV/rt(Hz) until the bandwidth is limited by the output buffer.  Adding a 10uF capacitor to the NR pin will roll off the noise bandwidth to about 8nV/rt(Hz).  This can be reduced further by increasing the size of the capacitor on the NR pin.

Summary:

Customer demand for precision voltage references with regulator-like drive has given rise to a new type of reference, called the “refulator.”  With its outstanding features, the LT6658 will serve a broad market for small, precision and low power applications.

MILPITAS, CA - October 11, 2016 - Linear Technology Corporation announces the LT3045, an ultralow noise, ultrahigh power supply ripple rejection (PSRR) low dropout voltage linear regulator, a higher output current version of the widely accepted 200mA LT3042 ultralow noise LDO. The LT3045’s unique design features ultralow spot noise of only 2nV/√Hz at 10kHz and 0.8μVRMS integrated output noise across a wide 10Hz to 100kHz bandwidth. Low and high frequency PSRR performance are exceptional. Low frequency PSRR exceeds 90dB out to 10kHz and high frequency PSRR exceeds 70dB out to 2.5MHz, thereby quieting noisy or high ripple input supplies. The LT3045 utilizes Linear’s proprietary LDO architecture – a precision current source reference followed by a high performance unity-gain buffer, resulting in virtually constant bandwidth, noise, PSRR and load regulation performance, independent of output voltage. In addition, this architecture permits paralleling of multiple LT3045s to further decrease noise, increase output current and spread heat on a printed circuit board.

The LT3045 delivers up to 500mA output current with a 260mV dropout voltage at full load, across a wide 1.8V to 20V input voltage range. Output voltage range is 0V to 15V and output voltage tolerance is highly accurate at ±2% over line, load and temperature. The device’s wide input and output voltage ranges, high bandwidth, high PSRR and ultralow noise performance are ideal for powering noise-sensitive applications such as PLLs, VCOs, mixers, LNAs, very low noise instrumentation, high speed/high precision data converters, medical applications such as imaging and diagnostics, precision power supplies and as a post-regulator for switching supplies.

The LT3045 operates with a small, low cost, 10μF ceramic output capacitor, optimizing stability and transient response. A single resistor programs the external precision current limit (±10% over temperature). A single SET pin capacitor lowers output noise and provides reference soft-start functionality, preventing output voltage overshoot at turn-on. Moreover, the device’s internal protection circuitry includes reverse-battery protection, reverse-current protection, internal current limit with foldback and thermal limit with hysteresis. Other features include fast start-up capability (useful if a large value SET pin capacitor is used) and a power good flag with programmable threshold to indicate output voltage regulation.

The LT3045 is available in thermally enhanced 10-lead 3mm x 3mm DFN (pin-compatible with the LT3042) and 12-lead MSOP packages, both with a compact footprint. The E- and I-grade versions are available from stock with an operating junction temperature of –40°C to 125°C. A future high temperature H-grade version will be rated from –40°C to 150°C. Devices are in stock, priced starting at $2.80 each for the E-grade in 1,000-piece quantities. For more information, visit www.linear.com/product/LT3045.

MILPITAS, CA - September 22, 2016 - Linear Technology Corporation announces a new higher temperature “H-grade” version of the LT3086 in the TSSOP package. The LT3086 is part of Linear’s feature-rich LDO+™ family, offering significant functionality previously unavailable in linear regulators. The 40V, 2.1A low dropout linear regulator (LDO) includes current monitoring with externally settable current limit and temperature monitoring with external control of thermal limit temperature. The device includes a programmable power good status flag, cable drop compensation and easy paralleling. The current reference in the LT308x LDO family provides regulation, independent of output voltage.

The LT3086 features a 1.4V to 40V input voltage range. A single resistor programs output voltage from 0.4V to 32V and dropout voltage is only 330mV at 2.1A. The LT3086 achieves line and load regulation of 0.1%, independent of output voltage. The trimmed, precision 50µA current reference is ±1% accurate, providing ±2% output voltage tolerance over line, load and temperature. Output voltage regulation, bandwidth, transient response and noise (40µVRMS) remain independent of output voltage due to the device’s unity gain voltage follower architecture.

Unique internal circuitry allows paralleling of multiple LT3086s for higher load current and heat spreading without needing external ballast resistors. Programmable cable drop compensation cancels regulation errors caused by line drops to the load. Output current and temperature monitoring, in addition to a power good flag with programmable threshold, provide system monitoring and diagnostic/debug capability. Internal fault circuitry includes thermal shutdown and current limit with foldback. Thermal limit and current limit are externally programmable. The device’s reverse-battery and reverse-current protection add robustness to the end design.

The LT3086HFE adjustable output version is offered in the thermally enhanced TSSOP surface mount package, specified with an operating junction temperature range of –40°C to 150°C.
