GAIN GND GENERAL DESCRIPTION The AD5674/AD5674R/AD5679/AD5679R are low power, 16-channel, 12-/16-bit, buffered voltage output, digital-toanalog converters (DACs) that include a 2.
5 V, 2 ppm/°C internal reference (enabled by default), and a gain select pin, resulting in a full-scale output of 2.
5 V (gain = 1) or 5 V (gain = 2).
The devices operate from a single, 2.
