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