LF353

Wide Bandwidth Dual JFET Input Operational Amplifier

General Description

These devices are low cost, high speed, dual JFET input

operational amplifiers with an internally trimmed input offset

voltage (BI-FET II™ technology). They require low supply

current yet maintain a large gain bandwidth product and fast

slew rate. In addition, well matched high voltage JFET input

devices provide very low input bias and offset currents. The

LF353 is pin compatible with the standard LM1558 allowing

designers to immediately upgrade the overall performance of

existing LM1558 and LM358 designs.

These amplifiers may be used in applications such as high

speed integrators, fast D/A converters, sample and hold

circuits and many other circuits requiring low input offset

voltage, low input bias current, high input impedance, high

slew rate and wide bandwidth. The devices also exhibit low

noise and offset voltage drift.
