LF453 Wide-Bandwidth Dual
JFET-Input Operational Amplifiers
General Description
The LF453 is a low-cost high-speed dual JFET-input oper-
ational amplifier with an internally trimmed input offset volt-
age (BI-FET II technology) The device requires a low supply
current and yet the amplifiers maintain a large gain band-
width product and a fast slew rate In addition well matched
high voltage JFET input devices provide very low input bias
and offset currents The LF453 is pin compatible with the
standard LM1558 allowing designers to upgrade the overall
performance of existing designs
The LF453 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
