description
This 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.
