ANALOG DEVICES AD8479TRZ-EP Operational Amplifier, 1 Channels, 8.8 V/µs, ± 2.5V to ± 18V, NSOIC, 8 Pins

AD8479-EP is a difference amplifier with a very high input common-mode voltage (VCM) range. It is a precision device that allows the user to accurately measure differential signals in the presence of high VCM upto ±600V dc. It can replace costly isolation amplifiers in applications that do not require galvanic isolation. The device operates over a ±600V dc VCM range and has inputs that are protected from common-mode or differential mode transients upto ±600V. It has low offset voltage, low offset voltage drift, low gain drift, low common-mode rejection drift, and excellent common-mode rejection ratio (CMRR) over a wide frequency range. It is used in applications such as avionics, unmanned systems, high voltage current sensing, motor controls, isolation.
