The AD5320 is a single, 12-bit buffered voltage out DAC that operates from a single +2.7 V to +5.5 V supply consuming 115 µA at 3 V. Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The AD5320 utilizes a versatile three-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI™,QSPI™, MICROWIRE™ and 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 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 part is put into power-down 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 0.7 mW at 5 V reducing to 1 μW in power-down mode. The AD5320 is one of a family of pin-compatible DACs. The AD5300 is the 8-bit version and the AD5310 is the 10-bit version. The AD5300/AD5310/AD5320 are available in 6-lead SOT-23 packages and 8-lead MSOP packages.
