The AD5687RBRUZ is a low power dual 12-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply, is guaranteed monotonic by design and exhibit less than 0.1% FSR gain error and 1.5mV offset error performance. The device includes a 2.5V, 2ppm/°C internal reference (enabled by default) and a gain select pin giving a full-scale output of 2.5 or 5V. It also incorporates a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. It also contains a per channel power-down feature that reduces the current consumption of the device to 4μA at 3V while in power-down mode. It uses a versatile serial peripheral interface (SPI) that operates at clock rates up to 50MHz and also contains a VLOGIC pin that is intended for 1.8/3/5V logic.
