Overview
The AD5686ARUZ-RL7, 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 precision and low power consumption, making it suitable for a variety of applications requiring accurate analog output.
The AD5686ARUZ-RL7 operates from a single 2.7 V to 5.5 V supply and features a gain select pin that allows for full-scale output of either 2.5 V or 5 V. It is available in a 16-lead TSSOP package and includes a power-on reset circuit and a RSTSEL pin to ensure the DAC outputs power up to zero scale or midscale until a valid write takes place.
