LF155 LF156 LF157 Series Monolithic JFET Input Operational Amplifiers December 1994 LF155 LF156 LF157 Series Monolithic JFET Input Operational Amplifiers General Description These are the first monolithic JFET input operational amplifiers to incorporate well matched high voltage JFETs on the same chip with standard bipolar transistors (BI-FETTM Technology) These amplifiers feature low input bias and offset currents low offset voltage and offset voltage drift coupled with offset adjust which does not degrade drift or monmode rejection The devices are also designed for high slew rate wide bandwidth extremely fast settling time low voltage and current noise and a low 1 f noise corner Advantages Y Replace expensive hybrid and module FET op amps Y Rugged JFETs allow blow-out free handling pared with MOSFET input devices Y Excellent for low noise applications using either high or low source impedance very low 1 f corner Y Offset adjust does not degrade drift or mon-mode...
