These devices are low cost, high speed, JFET input op amps, very low input offset voltage, and guaranteed input offset voltage drift. They require low supply current while maintaining a large gain-bandwidth product and fast slew rate. In addition, well-matched high voltage JFET input devices provide very low input bias and bias currents. The LF412 is pin-compatible with the LM1558, enabling designers to immediately upgrade the overall performance of existing designs.
These amplifiers can be used in applications requiring low input offset voltage and drift, low input bias current, high input impedance, high slew rate, and high bandwidth such as high-speed integration, fast D/A conversion, sample-and-hold circuits, and many others.
