    LTC1401 - Complete SO-8, 12-Bit, 200ksps ADC with Shutdown
    The LTC1401 is a complete 200ksps, 12-bit A/D converter that converts 0V to 2.048V unipolar input and draws only 15mW from a single 3V supply. This easy-to-use device comes complete with a 315ns sample-and-hold and a precision reference. Maximum DC specifications include ±1LSB INL, ±1LSB DNL and 45ppm/°C full-scale drift over temperature.The LTC1401 has three power saving modes: Nap and Sleep, through the serial interface and Shutdown by setting the SHDN pin to zero. In Nap mode, it consumes only 1.5mW of power and can wake up and convert immediately. In Sleep (Shutdown) mode, it consumes 19.5µW (13.5µW) of power typically. Upon power-up from Sleep or Shutdown mode, a reference ready (REFRDY) signal is available in the serial word to indicate that the reference has settled and the chip is ready to convert.The 3-wire serial port allows compact and efficient data transfer to a wide range of microprocessors, microcontrollers and DSPs.
