LF453 Product details

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 voltage JFET input devices provide very low input bias and offset currents The LF453 is pin compatible with the standard LM1558 allowing designers to upgrade the overall performance of existing designs
