The DAC8881 is a 16-bit, single-channel, voltage-output digital-to-analog converter (DAC)that offers low-power operation and a flexible SPI serial interface. It also features 16-bitmonotonicity, excellent linearity, and fast settling time. The on-chip precision output amplifierallows rail-to-rail output swing to be achieved over the full supply range of 2.7 V to 5.5V.

The device supports a standard SPI serial interface capable of operating with input dataclock frequencies up to 50 MHz. The DAC8881 requires an external reference voltage to set theoutput range of the DAC channel. A programmable power-on reset circuit is also incorporated intothe device to ensure that the DAC output powers up at zero-scale or midscale, and remains thereuntil a valid write command.

Additionally, the device has the capability to function in either unipolar straightbinary or 2’s complement mode. The DAC8881 provides a power-down feature, accessed over the PDNpin, that reduces the current consumption to 25 µA at 5 V. Power consumption is 6 mW at 5 V,reducing to 125 µW in power-down mode.

The DAC8881 is available in a 4 x 4 mm QFN-24 package with a specified operatingtemperature range of –40°C to +105°C.
