3 Description

This LF353 device is a low-cost, high-speed, JFETinput

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 highspeed

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.
