Overview
The AD5676RBRUZ-REEL7 is a low-power, octal, 12-/16-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the nanoDAC+ series and features a high-performance design with a 2.5 V, 2 ppm/°C internal reference. The AD5676RBRUZ-REEL7 operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. It includes a gain select pin that allows for a full-scale output of either 2.5 V or 5 V. The device is available in various packages, including 20-lead TSSOP, 20-lead LFCSP, and 16-ball WLCSP.
