Overview
The AD5686RBRUZ, produced by Analog Devices Inc., is a member of the nanoDAC+™ family. It is a low-power, quad, 16-bit buffered voltage output digital-to-analog converter (DAC). This device is designed for high accuracy and low power consumption, making it suitable for a variety of applications requiring precise analog output.
The AD5686RBRUZ operates from a single 2.7 V to 5.5 V supply and includes a 2.5 V, 2 ppm/°C internal reference. It features a gain select pin that allows for full-scale output of either 2.5 V or 5 V. The device is available in a 16-lead TSSOP package and is guaranteed monotonic by design, ensuring reliable performance.
