The AD5676BRUZ is a low power octal 16-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and is guaranteed monotonic by design. The device includes a gain select pin, giving a full-scale output of VREF or 2 x VREF. The internal power-on reset circuit and the RSTSEL pin of the AD5676 ensures that the output DAC power up to zero scale or midscale and then remain there until a valid write takes place. The AD5676 contains a per channel power-down mode that typically reduces the current consumption of the device to 1μA. The AD5676 employs a versatile serial peripheral interface (SPI) that operates at clock rates up to 50MHz and contains a VLOGIC pin intended for 1.8 to 5.5V logic.
