The DAC124S085 device is a full-featured, generalpurpose, quad, 12-bit, voltage-output, digital-toanalog converter (DAC) that can operate from a
single 2.7-V to 5.5-V supply and consumes 1.1 mW at 3 V and 2.4 mW at 5 V. The DAC124S085 is packaged in 10-pin WSON and VSSOP packages.
The 10-pin SON package makes the DAC124S085 the smallest quad 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. The reference for the DAC124S085 serves all four channels and can vary in voltage between 1 V and VA, providing the widest possible output dynamic range. The DAC124S085 has a 16-bit input shift register that controls the outputs to be updated, the mode of operation, the power down condition, and the binary input data. All four outputs can be updated simultaneously or individually depending on the setting of the two mode of operation bits.
