The DAC121S101-SEP device is a full-featured, general-purpose, 12-bit voltage-output digital-to-analog converter (DAC) that can operate from a single 2.7V to 5.5V supply and consumes just 177µA (typical) of current at 3.6V. The on-chip output amplifier allows rail-to-rail output swing and the three 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.

The supply voltage serves as the voltage reference for the DAC121S101-SEP, providing the widest possible output dynamic range. A power-on reset circuit powers up the DAC output to zero volts until there is a valid write to the device. A power-down feature reduces power consumption to less than a microwatt (typical).
