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
TM
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 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.
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
current is important, however, the LF351 is the better
choice.
