LF451 Product details

Description

The LF451 is a low-cost high-speed JFET-input operational amplifier with an internally trimmed input offset voltage (BIFET IITM 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 LF451 is pin compatible with the standard LM741 allowing designers to upgrade the overall performance of existing designs The LF451 may be u
