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 1,000 pF with no external compensation. Supply current is less than 500 A per amplifier at 30 V. Internal 500 series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal. Unlike previ……
