DAC121S101QML  
12-Bit Micro Power Digital-to-Analog Converter with Rail-  
to-Rail Output  
General Description  
Features  
The DAC121S101 is a full-featured, general purpose 12-bit  
voltage-output digital-to-analog converter (DAC) that can op-  
erate from a single +2.7 V to 5.5 V supply and consumes just  
177 µA of current at 3.6 V. The on-chip output amplifier allows  
rail-to-rail output swing and the three wire serial interface op-  
erates at clock rates up to 20 MHz over the specified supply  
voltage range and is compatible with standard SPI™, QSPI,  
MICROWIRE and DSP interfaces.

SYNC Interrupt Facility  
■
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 microWatt.
