Overview
The AD5676RARUZ-REEL7 is a low power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is part of the nanoDAC+ series and is known for its high performance and precision. It includes a 2.5 V internal reference with a low drift of 2 ppm/°C and a gain select pin that allows for full-scale output of either 2.5 V or 5 V. The AD5676R operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design.
