OP2177ARMZ Description
The OP2177ARMZ consists of very high precision, single, dual, and quad amplifiers featuring extremely low offset voltage and
drift, low input bias current, low noise, and low power consumption. Outputs are stable with capacitive loads of over 1000 pF
with no external compensation. The supply current is less than 500 μA per amplifier at 30 V. Internal 500 Ω series resistors protect the
inputs, allowing input signal levels several volts beyond either supply without phase reversal.
