AD5693RACPZ-RL7

AD5693R is a low power, single-channel, 16bit buffered voltage output DAC. It includes an enabled by default internal 2.5V reference, offering 2ppm/°C drift. The output span can be programmed to be 0V to VREF or 0V to 2 × VREF. All devices operate from a single 2.7V to 5.5V supply and are guaranteed monotonic by design. 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. It contains a power-down mode that reduces the current consumption of the device to 2µA (maximum) at 5V and provides software selectable output loads. Application includes process controls, data acquisition systems, digital gain and offset adjustment, programmable voltage sources, optical modules.
