DAC121S101QCMK/NOPB

The DAC121S101QCMK/NOPB is a full-featured general-purpose 12-bit voltage-output Digital-to-analog Converter (DAC) operates from a single 2.7 to 5.5V supply and consumes just 177µA of current at 3.6V. The on-chip output amplifier allows rail-to-rail output swing and the 3-wire serial interface operates at clock rates up to 30MHz over the specified supply voltage range and is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. Competitive devices are limited to 20MHz clock rates at supply voltages in the 2.7 to 3.6V range. The supply voltage for the DAC121S101 serves as its voltage reference, providing the widest possible output dynamic range. A power-on reset circuit ensures that the DAC output powers up to zero volts and remains there until there is a valid write to the device. A power-down feature reduces power consumption to less than a µW.
