Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5320 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard QSPI , MICROWIRE and digital signal processing DSP interface standards. The reference for AD5320 is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to zero volts and remains there until a valid write takes place to the device. The part contains a powerdown 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 part is put into powerdown mode over the serial interface. The low power consumption of this part in normal operation makes it ideally suited to portable, battery-operated equipment. The power consumption is mW at 5 V reducing to 1 uW in power-down mode.
