3 Description
This LF353 device is a low-cost, high-speed, JFET-
input operational amplifier with very low input offset
voltage. 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 LF353 can be used in applications such as high-
speed integrators, digital-to-analog converters,
sample-and-hold circuits, and many other circuits.
The LF353 is characterized for operation from 0°C to
70°C.
