LF412 Low Offset, Low Drift Dual JFET Input Operational Amplifier August 2000 LF412 Low Offset, Low Drift Dual JFET Input Operational Amplifier General Description These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and guaranteed 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 dual is pin compatible with the LM1558, allowing designers to immediately upgrade the overall performance of existing designs.
