LF147/LF347
Wide Bandwidth Quad JFET Input Operational Amplifiers
General Description
The LF147 is a low cost, high speed quad JFET input opera-
tional 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. The LF147 is pin compatible with the standard
LM148. This feature allows designers to immediately up-
grade 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 offset voltage,
low input bias current, high input impedance, high slew rate
and wide bandwidth. The device has low noise and offset
voltage drift.
