3 Description
These devices are low cost, high speed, JFET input
operational amplifiers with very low input offset
voltage and 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-N-MIL 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 impedance, high slew rate and wide
bandwidth.
