AD5449 Overview
The AD5429/AD5439/AD54491 are CMOS 8-, 10-, and 12-bit dual-channel current output digital-to-analog converters, respectively. These devices operate from a 2.5 V to 5.5 V power supply, making them suited to battery-powered and other applications. The applied external reference input voltage (VREF) determines the full-scale output current.
