Manufacturer's Description

The AD5624/AD5664, members of the nanoDAC family, are low power, quad, 12-, 16-bit buffered voltage-out DACs that operate from a single 2.7 V to 5.5 V supply and are guaranteed monotonic by design. The AD5624/AD5664 require an external reference voltage to set the output range of the DAC. The part incorporates a poweron reset circuit that ensures the DAC output powers up to 0 V and remains there until a valid write takes place. The parts contain a power-down feature that reduces the current consumption of the device to 480 nA at 5 V and provides software-selectable output loads while in power-down mode. The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 2.25 mW at 5 V, going down to 2.4 μW in power-down mode. The AD5624/AD5664 on-chip precision output amplifier allows rail-to-rail output swing to be achieved.
