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.
