Low power 12-bit accuracy guaranteed Guaranteed 16-bit monotonic by design

The AD5662, a member of the nanoDAC family, is a low powsingle, 16-bit buffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply and is guaranteed monotonic by design. The AD5662 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V (AD5662x-1) or to midscale (AD5662x-2), and remains there until a valid write takes place. The part contains a power-dowfeature 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 this part in normal operation makes it ideally suited to portable battery-operated equipmenThe power consumption is 0.75 mW at 5 V, going down to 2.4 μW in power-down mode. The AD5662’s on-chip precision output amplifier allows rail-to- rail output swing to be achieved. For remote sensing applications,the output amplifier’s inverting input is available to the user.
