The DAC8564 incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device. The device contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 1.3A at 5V. The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The power consumption is 2.9mW at 3V, reducing to 1.5W in power-down mode.
