The AD5663ARMZ is a low power dual 16-bit buffered voltage-out Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and is guaranteed monotonic by design. The AD5663 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 0V 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 480nA at 5V 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 many applications. The power consumption is 1.25mW at 5V going down to 2.4μW in power-down mode. It uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz and is compatible with standard SPI?, QSPI?, MICROWIRE? and DSP interface standards.
