The 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 ±600 V. The AD8479 can replace costly isolation amplifiers in applications that do not require galvanic isolation.
