LF451 Wide-Bandwidth
JFET-Input Operational Amplifier
General Description
The LF451 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 cur-
rent 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 cur-
rents. The LF451 is pin compatible with the standard
LM741, allowing designers to upgrade the overall perform-
ance 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.
