description
This device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage and
a maximum input offset voltage drift. It requires low supply current, yet maintains a large gain-bandwidth product
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.
