DAC122S085CIMM/NOPB

The DAC122S085CIMM/NOPB is a full-featured general purpose dual 12-bit voltage-output Digital-to-analog Converter (DAC) that can operate from a single 2.7 to 5.5V supply and consumes 0.6mW at 3V and 1.6mW 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. Competitive devices are limited to 25MHz clock rates at supply voltages in the 2.7 to 3.6V range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE and DSP interfaces. The reference for the DAC serves all four channels and can vary in voltage between 1V and VA, providing the widest possible output dynamic range. The DAC 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. Both outputs can be updated simultaneously or individually depending on the setting of the two modes of operation bits.
