The AD5313ARUZ is a dual 10-bit buffered voltage output Digital-to-analog Converter (DAC) operates from a single 2.5 to 5.5V supply, consuming 230μA at 3V. Its on-chip output amplifier allows the outputs to swing rail-to-rail with a slew rate of 0.7V/μs. The AD5313 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 devices incorporate a power-on reset circuit, which ensures that the DAC outputs power up to 0V and remain there until a valid write to the device takes place. There is also an asynchronous active low CLR pin that clears DAC to 0V. The outputs of DAC can be updated simultaneously using the asynchronous LDAC input. The device 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.
