AD5691RBRMZ

AD5691RBRMZ is a low power, single-channel, buffered voltage output DAC. The output span can be programmed to be 0V to VREF or 0V to 2 × 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. 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. Typical applications are process controls, data acquisition systems, digital gain and offset adjustment programmable voltage sources, optical modules.
