LF411

Low Offset, Low Drift JFET Input Operational Amplifier

General Description

These devices are low cost, high speed, JFET input opera-

tional amplifiers with very low input offset voltage and guar-

anteed input offset voltage drift. They require low supply cur-

rent yet maintain a large gain bandwidth product and fast

slew rate. In addition, well matched high voltage JFET input

devices provide very low input bias and offset currents. The

LF411 is pin compatible with the standard LM741 allowing

designers to immediately upgrade the overall performance of

existing designs.

These amplifiers may be used in applications such as high

speed integrators, fast D/A converters, sample and hold cir-

cuits and many other circuits requiring low input offset volt-

age and drift, low input bias current, high input impedance,

high slew rate and wide bandwidth.
