Product Summary

The LF412MJ/883 is a low cost, high speed, JFET input operational amplifier with very low input offset voltage and guaranteed input offset voltage drift. It requires 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 LF412MJ/883 dual is pin compatible with the LM1558, allowing designers to immediately upgrade the overall performance of existing designs. The LF412MJ/883 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.
