The ADA4177-4ARUZ is a precision quad Operational Amplifier features low offset voltage (2μV typical) and drift (1μV/°C maximum), low input bias current, low noise and low current consumption (500μA typical). Outputs are stable with capacitive loads of more than 1000pF with no external compensation. The inputs of the ADA4177-4 set a new standard in precision amplifier robustness, providing input protection against signal excursions 32V beyond either supply, as well as 70dB of rejection for electromagnetic interference (EMI) at 1000MHz. Applications for this amplifier include sensor signal conditioning (such as thermocouples, RTDs and strain gages), process control front-end amplifiers and precision diode power measurement in optical and wireless transmission systems.
