The LF412CN/NOPB is a high-speed dual JFET input Operational Amplifier with very low input offset voltage and input offset voltage drift and require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input device 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 is 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.
