LF451 Datasheet Lf451 Wide-bandwidth JFET-input Operational Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LF451 Wide-Bandwidth JFET-Input Operational Amplifier December 1995 LF451 Wide-Bandwidth JFET-Input Operational.

General 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 patible with the standard LM741 allowing designers to upgrade the overall performance of existing designs The LF451 may be used in such applications 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
