The H (Metal Can), J (Ceramic), and K (Metal Can) Packages From Linear Technology Are Now Obsolete Both devices have lower input bias and offset currents over the entire temperature range, and are available in all standard 8-pin packages. In addition, Linear's LF412A has lower voltage noise and higher voltage gain. Linear's OP-215 supply currents are nearly halved. Please see the LT1057/LT1058 data sheet for applications requiring higher performance. The LT1057 is a pin compatible JFET input dual, the LT1058 is a JFET input quad op amp in the standard 14-pin DIP configuration.
