LF147 - Texas Instruments

LF147 Wide Bandwidth Quad JFET Input Operational Amplifiers

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 cur.
