LH0042
Low Cost FET Op Amp
General Description
The LH0042 is a FET input operational amplifier with very
high input impedance and low input currents with no com-
promise in noise common mode rejection ratio open loop
gain or slew rate The LH0042 is internally compensated
and is free of latch-up
The LH0042 is specified for operation over the b55 C to
a125 C military temperature range The LH0042C is speci-
fied for operation over the b25 C to a85 C temperature
range
The LH0042 op amp is intended to fulfill a wide variety of
applications for process control medical instrumentation
and other systems requiring very low input currents The
LH0042 provides low cost high performance for such appli-
cations as electrometer and photocell amplification pico-
ammeters and high input impedance buffers
