The AD5694ARUZ is a low power quad 16-bit buffered voltage output Digital-to-Analog Device (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. It includes a gain select pin giving a full-scale output of 2.5 or 5V. It incorporates a power-on reset circuit and a RSTSEL pin, the RSTSEL pin ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. It contains a per-channel power-down feature that reduces the current consumption of the device in power-down mode to 4μA at 3V. It uses versatile 2-wire serial interface that operates at clock rates up to 400kHz and includes a VLOGIC pin intended for 1.8/3/5V logic.
