The AD5641 contains a power-down feature that reduces current consumption to <100 nA at 3 V, and provides softwareselectable output loads while in power-down mode. The part is put into power-down mode over the serial interface. The low power consumption of the part in normal operation makes it ideally suited to portable batter y-operated equipment. The combination of small package and low power makes this nanoDAC device ideal for level-setting requirements such as generating bias or control voltages in space-constrained and power-sensitive applications.
