The DAC8531 is a low-power, single, 16-bit buffered voltage output Digital-to-Analog Converter (DAC). Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. The DAC8531 uses a versaTIle three-wire serial interface that operates at clock rates up to 30MHz and is compaTIble with standard SPI™, QSPI™, Microwire™, and Digital Signal Processor (DSP) interfaces.
The DAC8531 requires an external reference voltage to set the output range of the DAC. The DAC8531 incorporates a power-on reset circuit that ensures that the DAC output powers up at 0V and remains there unTIl a valid write takes place to the device. The DAC8531 contains a power-down feature, accessed over the serial interface, that reduces the current consumpTIon of the device to 200nA at 5V.
