Description

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-bit monotonicity, excellent linearity, and fast settling time. The on-chip precision output amplifier allows rail-to-rail output swing to be achieved over the full supply range of 2.7 V to 5.5 V.

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

Additionally, the device has the capability to function in either unipolar straight binary or 2’s complement mode. The DAC8881 provides a power-down feature, accessed over the PDN pin, 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 operating temperature range of –40°C to +105°C.
