The LH0042 is a FET input operational amplifier with very high input impedance and low input currents with no compromise in noise, common mode rejection ratio, open loop gain, or slew rate. The LH0042 is internally ompensated and is free of latch-up.

The LH0042 is specified for operation over the -55 to +125 military temperature range. The LH0042C is specified for operation over the -25 to +85 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 applications as electrometer and photocell amplification, picoammeters, and high input impedance buffers.
