AD7248AAQ

Overview

The AD7248AAQ is a high-speed, monolithic 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a parallel word input interface and utilizes a current-steering architecture to achieve fast settling times. The device is housed in a ceramic dual in-line package (CDIP-24), designed for military and aerospace environments. Key electrical characteristics include a full-scale output current range and precise linearity specifications typical of the AD7248 family. It operates with single or split power supplies and includes internal reference capabilities.
