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 dual is pin compatible with the LM 1558, allowing designers
o 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.
