AD8479-EP Description

The AD8479-EP is a difference amplifier with a very high input common-mode voltage (VCM) range. The AD8479-EP is a precision device that allows the user to accurately measure differential signals in the presence of high VCM up to ±600 V dc.

The AD8479-EP can replace costly isolation amplifiers in applications that do not require galvanic isolation. The device operates over a ±600 V dc VCM range and has inputs that are protected from common-mode or differential mode transients up to ±600 V.

The AD8479-EP 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-EP is available in a space-saving 8-lead SOIC package and is operational over the −55°C to +125°C temperature range.

Additional application and technical information can be foundin the AD8479 data sheet.
