AD8479ARZ

AD8479 is a difference amplifier with a very high input common-mode voltage range. The AD8479 is a precision device that allows the user to accurately measure differential signals in the presence of high common-mode voltages up to ±600V. The AD8479 can replace costly isolation amplifiers in applications that do not require galvanic isolation. The device operates over a ±600V common-mode voltage range and has inputs that are protected from common-mode or differential mode transients up to ±600V. It is suitable for use in high voltage current sensing, battery cell voltage monitors, power supply current monitors, motor controls and isolation applications.
