OP1177AR Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The OPx177 family 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. 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.

●FEATURES

●Low offset voltage: 60 μV maximum

●Very low offset voltage drift: 0.7 μV/°C maximum

●Low input bias current: 2 nA maximum

●Low noise: 8 nV/√Hz typical

●CMRR, PSRR, and A

●VO
