LF351 Wide Bandwidth JFET Input Operational Amplifier

General Description

The LF351 is a low cost high speed JFET input operational

amplifier with an internally trimmed input offset voltage

(BI-FET II^TMtechnology). 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 LF351 is pin compatible with the standard

LM741 and uses the same offset voltage adjustment circuit-

ry. This feature allows designers to immediately upgrade the

overall performance of existing LM741 designs.

current is important, however, the LF351 is the better

choice.

The LF351 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 device has low noise and offset

voltage drift, but for applications where these requirements

are critical, the LF356 is recommended. If maximum supply
