DESCRIPTION

This device is a low cost, high speed, JFET input

operational amplifier with very low input offset voltage

and ensured input offset voltage drift. It requires low

supply current yet maintains 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.

This amplifier 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.
