LF147QML - Wide Bandwidth Quad JFET Input Operational Amplifiers

General Description

The LF147 is a low cost, high speed quad JFET input operational amplifier with an internally trimmed input offset voltage ( BI-FET II™ technology).

The device requires a low supply current and yet maintains a large gain bandwidth product and a fast slew rate.
