Overview
The AD5675BRUZ-REEL7, produced by Analog Devices Inc., is a low power, octal, 16-bit buffered voltage output digital-to-analog converter (DAC). This device is part of the nanoDAC+ series and is designed for high precision and versatility. It operates from a single 2.7 V to 5.5 V power supply and features a gain select pin, allowing for full-scale output of VREF (gain = 1) or 2 × VREF (gain = 2). The AD5675 is guaranteed monotonic by design and includes a power-on reset circuit and a RSTSEL pin to ensure the output DACs power up to zero scale or midscale until a valid write takes place.
