description

This device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage and

amaximuminputoffsetvoltagedrift. Itrequireslowsupplycurrent, yetmaintainsalargegain-bandwidthproduct

and a fast slew rate. In addition, the matched high-voltage JFET input provides very low input bias and offset

currents.

The LF411 can be used in 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.

Input bias currents of an FET-input operational amplifier are normal junction reverse currents, which are temperature sensitive. Pulse techniques

must be used that will maintain the junction temperatures as close to the ambient temperature as possible.
