These devices are low cost, high speed, JFET input operational
amplifiers with very low input offset voltage and guaranteed
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
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 circuits
and many other circuits requiring low input offset voltage
and drift, low input bias current, high input impedance,
high slew rate and wide bandwidth.
