The DAC084S085CIMM/NOPB is a full-featured general-purpose QUAD 8-bit voltage-output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and consumes 1.1mW at 3V and 2.5mW at 5V. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 40MHz over the entire supply voltage range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE and DSP interfaces. The reference for the DAC084S085 serves all four channels and can vary in voltage between 1V and VA, providing the widest possible output dynamic range. The DAC084S085 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 modes of operation bits.
