Overview
The AD5676BRUZ is a low-power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This device is designed for high-performance applications and features a user-selectable gain of 1 or 2, allowing for full-scale output of VREF or 2 × VREF. The AD5676BRUZ operates from a single 2.7 V to 5.5 V power supply and is guaranteed monotonic by design. It includes an internal power-on reset circuit and a RSTSEL pin, ensuring that the output DACs power up to zero scale or midscale and remain there until a valid write takes place. The device also supports a per-channel power-down mode, significantly reducing current consumption to 1 µA.
