The DAC7678 incorporates a power-on-reset circuit that ensures the DAC output powers up to either zero-scale or mid-scale until a valid code is written to the device. These devices contain a power-down feature, accessed over the serial interface that reduces the current consumption of the device to typically 0.42mA at 5V. Power consumption (including internal reference) is typically 3.56mW at 3V, reducing to 0.68mW in power-down mode. The low power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The DAC7678 is drop-in and
