The AD8273 is a low distortion, dual-channel amplifier with internal gain setting resistors. With no external components, it can be configured as a high performance difference amplifier (G = ½ or 2), inverting amplifier (G = ½ or 2), or noninverting amplifier (G = 1½ or 3).
The AD8273 operates on both single and dual supplies and only requires 2.5 mA maximum supply current for each amplifier. It is specified over the industrial temperature range of −40°C to +85°C and is fully RoHS compliant.

Evaluation Kits (1)
The design of this board emphasizes simplicity and ease of use. This board comes with a ready assortment of connection options (BNC and RCA connectors), and many configurations are set by jumpers.
The AD8273, AD8277, AD8279 data sheets, available at www.analog.com, cover the details of the device’s operation. Using these data sheets for reference will help designers in their end application. The data sheets are helpful for understanding the operation of the AD8273/AD8277/AD8279 evaluation board, especially during the initial configuration and when powering up for the first time.
