Product Summary
The LF147J 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 device provides very low input bias and offset currents. The LF147J is pin compatible with the standard LM148. This feature allows designers to immediately upgrade the overall performance of existing LF148 and LM124 designs. The LF147J 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 LF147J has low noise and offset voltage drift.
