LF147/LF347
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
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 stan-
dard 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 offset voltage,
low input bias current, high input impedance, high slew rate
and wide bandwidth. The device has low noise and offset
voltage drift.
