LF412
Low Offset, Low Drift Dual 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
current 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
LF412 dual is pin compatible with the LM1558, 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
circuits and many other circuits requiring low input offset
voltage and drift, low input bias current, high input imped-
ance, high slew rate and wide bandwidth.
