The on-chip output amplifier allows rail-torail output swing and the three wire serial interface operates at clock rates up to 30 MHz over the specified supply voltage range and is patible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. petitive devices are limited to 20-MHz clock rates at supply voltages in the 2.7 V to 3.6 V 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 micro Watt. The low power consumption and small packages of the DAC121S101 make it an excellent choice for use in battery operated equipment.
