The AD53201 is a single， 12-bit buffered voltage out digital-toanalog converter （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 3-wire serial interface that operates at clock rates up to 30 MHz and is compatible with standard SPI®， 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.
