MICROCIRCUIT DATA SHEET

WIDE BANDWIDTH QUAD JFER INPUT OPERATIONAL AMPLIFIER

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[TM] 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. The LF147 is pin compatible with the standard LM148. This feature allows

designers to immediately upgrade the overall performance of existing LF148 and LM124

designs.

The LF147 may be used in applications such as high speed integrators, fast D/A converters,

sample-and-hold circuits and many other circuits requiring low input bias current, high

input impedance, high slew rate and wide bandwidth. The device has low noise and offset

voltage drift.
