An Introduction of LF353 Operational Amplifier

Description

This LF353 device is a low-cost, high-speed, JFET-input operational amplifier with very low input offset voltage. It requires a 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.
