Product Summary

The LF412CN is a Low Offset, Low Drift Dual JFET Input Operational Amplifier with very low input offset voltage and guaranteed input offset voltage drift. The LF412CN 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 LF412CN dual is pin compatible with the LM1558, allowing designers to immediately upgrade the overall performance of existing designs.
