These devices contain a power-down feature that reduces current consumption to typically 550 nA at 5 V. The DACx圆2 devices incorporate a power-on-reset circuit that ensures the DAC output powers up and remains at zero scale until a valid code is written to the device, whereas the DACx圆3 devices similarly power up at mid-scale. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces. They use a versatile three-wire serial interface that operates at clock rates up to 50 MHz.

These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). The internal reference has an initial accuracy of ±5 mV and can source or sink up to 20 mA at the V REFIN/V REFOUT pin. These devices include a 2.5-V, 4-ppm/☌ internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The DAC756x, DAC816x, and DAC856x devices are low-power, voltage-output, dual-channel, 16-, 14-, and 12-bit digital-to-analog converters (DACs), respectively.
