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. The device operates over a ±600 V common-mode voltage range and has inputs that are protected from common-mode or differential mode transients up 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

Product Detail

The AD8479R-EBZ is specifically designed to aid the evaluation of the AD8479, a very high common-mode voltage precision difference amplifier. The design of this board emphasizes simplicity and ease of use. This board comes with connection options for the input and output terminals (SMA and Vector pins) and a predefined configuration with the reference pins both tied to ground.


See the AD8479R-EBZ documentation and AD8479 data sheet for additional information.
