June 2005 .. DAC121S101 12-Bit Micro Power Digital-to-Analog Converter with Rail-to-Rail Output DAC121S101 12-Bit Micro Power Digital-to-Analog Converter with Rail-to-Rail Output General Description 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 patible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. petitive devices...
