The AD5693RBRMZ is a low power 1-channel 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 output span can be programmed to be 0V to VREF or 0V to 2 x VREF. The internal power-on reset circuit ensures that the DAC register is written to zero scale at power-up while the internal output buffer is configured in normal mode. The DAC contains a power-down mode that reduces the current consumption of the device to 2μA maximum at 5V and provides software selectable output loads. It uses an I2C interface.
