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.

In addition, well matched high voltage JFET input devices provide very low input bias and offset currents.
