OP4177ARZ Datasheet PDF - ADI

●The OP4177ARZ is a very high precision quad Operational Amplifier features extremely low offset voltage and drift, low input bias current, low noise and low power consumption. Outputs are stable with capacitive loads of over 1000pF with no external compensation. Supply current is less than 500µA per amplifier at 30V. Internal 500R series resistors protect the inputs, allowing input signal levels several volts beyond either supply without phase reversal. Applications for this amplifier include precision diode power measurement, voltage and current level setting and level detection in optical and wireless transmission systems. Additional applications include line-powered and portable instrumentation and controls-thermocouple, RTD, strain-bridge and other sensor signal conditioning and precision filters.
