The OP777ARMZ is a precision single Operational Amplifier features micropower operation and rail-to-rail output ranges. This amplifier provides improved performance over the industry-standard OP07 with ±15V supplies and offers the further advantage of true single-supply operation down to 3V. Outputs are stable with capacitive loads of over 500pF. Supply current is less than 300μA per amplifier at 5V. 500R series resistors protect the inputs, allowing input signal levels several volts above the positive supply without phase reversal.
