The AD5322BRMZ is a 12-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.5 to 5.5V supply, consuming 230μA at 3V. Their on-chip output amplifiers allow the outputs to swing rail-to-rail with a slew rate of 0.7V/μs. The AD5322 utilizes a versatile 3-wire serial interface that operates at clock rates up to 30MHz and is compatible with standard SPI?, QSPI?, MICROWIRE? and DSP interface standards. The outputs of DAC can be updated simultaneously using the asynchronous LDAC input. The part incorporates a power-on reset circuit, which ensures that the DAC outputs power-up to 0V and remain there until a valid write takes place to the device. The part contains a power-down feature that reduces the current consumption of the devices to 200nA 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 for portable battery-operated equipment.
