LF453 - LF453 Wide-Bandwidth Dual JFET-Input Operational Amplifiers

Description

The LF453 is a low-cost high-speed dual JFET-input operational amplifier with an internally trimmed input offset voltage (BI-FET II technology) The device requires a low supply current and yet the amplifiers maintain a large gain bandwidth product and a fast slew rate In addition well matched high v
