1.4 Device Information

The DAC121S101 device is a full-featured, general-purpose, 12-bit voltage-output digital-to-analog (DAC) that can operate from a single 2.7V to 5.5V supply and consumes just 177µA of current. 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. Competitive devices are limited to 20MHz clock rates at supply voltages in the 2.7V to 3.6V range.

The supply voltage for the DAC121S101 serves as the voltage reference, providing the widest possible output dynamic range. A power-on reset circuit verifies 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 microWatt.

The low power consumption and small packages of the DAC121S101 makes the device an excellent choice for use in battery operated equipment.
