The DAC7568, DAC8168, and DAC8568 incorporate a power-on-reset circuit that ensures the DAC output powers up at either zero scale or midscale until a valid code is written to the device. These devices contain a power-down feature, accessed over the serial interface, that reduces current consumption to typically 0.18A at 5V. Power consumption (including internal reference) is typically 2.9mW at 3V, reducing to less than 1W in power-down mode. The low power consumption, internal reference, and small footprint make these devices ideal for portable, battery-operated equipment.
