Overview
The AD5317RBRUZ-RL7, produced by Analog Devices Inc., is a low power, quad, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) that belongs to the nanoDAC® family. This device features a 2.5 V, 2 ppm/°C internal reference and a gain select pin, allowing for full-scale output of either 2.5 V or 5 V. It operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design, ensuring high accuracy with less than 0.1% Full-Scale Range (FSR) gain error and 1.5 mV offset error performance.
