Product Summary

The LF156H is the first monolithic JFET input operational amplifier to incorporate well matched, high voltage JFETs on the same chip with standard bipolar transistors (BI-FET Technology). The LF156H features low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust which does not degrade drift or common-mode 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.

Features

LF156H features: (1)Replace expensive hybrid and module FET op amps; (2)Rugged JFETs allow blow-out free handling compared with MOSFET input devices; (3)Excellent for low noise applications using either high or low source impedance, very low 1/f corner; (4)Offset adjust does not degrade drift or common-mode rejection as in most monolithic amplifiers; (5)New output stage allows use of large capacitive loads (5,000 pF) without stability problems; (6)Internal compensation and large differential input voltage capability.
