This device is a low-cost, high-speed, FET-Input operational amplifier with very low input offset voltage and a maximum input offset voltage drift. This device requires low supply current, yet maintains a large gain-bandwidth product and a fast slew rate. In addition, the matched high-voltage FET input provides very low input bias and offset currents.

The LF411 is designed for applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.

The LF411C is characterized for operation from 0°C to 70°C. The LF411I is characterized for operation from –40°C to +85°C.
