The AD5662 requires an external reference voltage to set the output range of the DAC. The part incorporates a power-onreset circuit that ensures the DAC output powers up to 0 V (AD5662x-1) or 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 200 nA at 5 V, and provides software selectable output loads while in power-down mode.
The low power consumption of this part AD5662 in normal operation makes it ideally suited to portable battery-operated equipment. The power consumption is 0.7 mW at 5 V, reducing to 1 W in power-down mode.
The AD5662's on-chip precision output amplifier allows rail-torail output swing to be achieved. The AD5662 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30 MHz, and is compatible with standard SPI™, QSPI™, MICROWIRE™, and DSP interface standards.
