Analog Devices Inc. AD5689/AD5689R Dual 16-Bit nanoDAC+

Analog Devices AD5689/AD5689R Dual 16-Bit nanoDAC+™ is a member of the nanoDAC+™ family low power, dual, 16-bit, buffered voltage output digital-to-analog converter (DAC). This device includes a gain select pin giving a full-scale output of 2.5V (gain = 1) or 5V (gain = 2). The AD5689 operates from a single 2.7V to 5.5V supply, is guaranteed monotonic by design, and exhibits less than 0.1% FSR gain error and 1.5mV offset error performance. 

The AD5689/AD5689R DAC also incorporates a power-on reset circuit and a RSTSEL pin to ensure the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Analog Devices AD5689/AD5689R Dual 16-Bit nanoDAC+ contain a per-channel power-down feature that reduces the current consumption of the device to 4μA at 3V while in power-down mode.
