Overview
The AD5697RBRUZ-RL7, produced by Analog Devices Inc., is a low-power, dual, 12-bit buffered voltage output digital-to-analog converter (DAC) and a member of the nanoDAC+™ family. This device features a 2.5 V, 2 ppm/°C internal reference and a gain select pin, allowing for full-scale outputs of 2.5 V or 5 V. It operates from a single 2.7 V to 5.5 V supply and is available in a 3 mm × 3 mm LFCSP and a TSSOP package.
