National Semiconductor DAC121S101
The DAC121S101 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 177 µA of current at 3.6 Volts. The on-chip output amplifier allows rail-to-rail output swing and the three wire serial interface operates at clock rates up to 30 MHz over the specified supply voltage range and is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. The supply voltage for the DAC121S101 serves as its voltage reference, providing the widest possible output dynamic range.| Part No. | DAC121S101 |

GENERAL DESCRIPTION
Competitive devices are limited to 20 MHz clock rates at supply voltages in the 2.7V to 3.6V 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 microWatt. The low power consumption and small packages of the DAC121S101 make it an excellent choice for use in battery operated equipment. The DAC121S101 is a direct replacement for the AD5320 and the DAC7512 and is one of a family of pin compatible DACs, including the 8-bit DAC081S101 and the 10-bit DAC101S101. The DAC121S101 operates over the extended industrial temperature range of −40˚C to +105˚C.FEATURES
