The DAC082S085 device is a full-featured, general-purpose, DUAL, 8-bit, voltage-output, digital-to-analog converter (DAC) that can operate from a single 2.7-V to 5.5-V supply and consumes 0.6 mW at 3 V and 1.6 mW at 5 V. The DAC082S085 is packaged in 10-pin SON and VSSOP packages. The 10-pin WSON package makes the DAC082S085 the smallest DUAL DAC in its class. The on-chip output amplifier allows rail-to-rail output swing, and the three-wire serial interface operates at clock rates up to 40 MHz over the entire supply voltage range. Competitive devices are limited to 25-MHz clock rates at supply voltages in the 2.7 V to 3.6 V range. The serial interface is compatible with standard SPI™, QSPI, MICROWIRE, and DSP interfaces.
