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-down feature that reduces the current consumption of the device to 480 n A 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 equipment. The power consumption is 0.75 m W at 5 V, going down to 2.4 μW in power-down mode. The AD5662’s on-chip precision output amplifier allows rail-torail output swing to be achieved. For remote sensing applications, the output amplifier’s inverting input is available to the user. Rev. A Information furnished by Analog Devices is believed to be accurate and reliable.
