The AD8479 is a difference amplifier with a very high inputcommon-mode voltage range. The AD8479 is a precision devicethat allows the user to accurately measure differential signals inthe presence of high common-mode voltages up to ±600 V.The AD8479 can replace costly isolation amplifiers in applicationsthat do not require galvanic isolation. The device operates overa ±600 V common-mode voltage range and has inputs that areprotected from common-mode or differential mode transientsup to ±600 V.The AD8479 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.The AD8479 is available in a space-saving 8-lead SOIC package and is operational over the −40°C to +125°C temperature range.Applications High voltage current sensing Battery cell voltage monitors Power supply current monitors Motor controls Isolation
