~National ~ Semiconductor Amplifiers LH00221LH0022C High Performance FET Op Amp LH00421LH0042C· Low Cost FET Op Amp LH00521LH0052C Precision FET Op Anip General Description The LH0022/LH0042/LH0052 are a family of FET input operational amplifiers with very closely matched input characteristics, very high input impedance, and ultra-low input currents with no compromise in noise, common mode rejection ratio, open loop gain, or slew rate_ The internally laser nulled LH0052 offers 500 microvolts maxi- tcmum offset and 5 pV offset drift_ Input offset current is less than 500 femtoamps at room temperature and 500 pA maximum at 125°C. The LH0022 and LH0042 are not internally nulled but offer comparable matching characteristics. All devices in the family are internally compensated and are free of latch-up and unusual oscillation problems. The devices may be offset nulled with a single 10k trimpot with neglible effect in CMRR. The LH0022, LH0042 and LH0052 are specified for operation ove...
