DAC122S085  
12-Bit Micro Power DUAL Digital-to-Analog Converter with  
Rail-to-Rail Output  
General Description  
Features  
The DAC122S085 is a full-featured, general purpose DUAL  
12-bit voltage-output digital-to-analog converter (DAC) that  
can operate from a single +2.7V to 5.5V supply and consumes  
0.6 mW at 3V and 1.6 mW at 5V. The DAC122S085 is pack-  
aged in 10-lead LLP and MSOP packages. The 10-lead LLP  
package makes the DAC122S085 the smallest DUAL DAC in  
its class. The on-chip output amplifier allows rail-to-rail output  
swing and the three wire serial interface operates at clock  
rates up to 40 MHz over the entire supply voltage range.  
Competitive devices are limited to 25 MHz clock rates at sup-  
ply voltages in the 2.7V to 3.6V range. The serial interface is  
compatible with standard SPI™, QSPI, MICROWIRE and  
DSP interfaces.

The reference for the DAC122S085 serves all four channels  
and can vary in voltage between 1V and VA, providing the  
widest possible output dynamic range. The DAC122S085 has  
a 16-bit input shift register that controls the outputs to be up-  
dated, the mode of operation, the powerdown condition, and  
the binary input data. Both outputs can be updated simulta-  
neously or individually depending on the setting of the two  
mode of operation bits.

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 con-  
sumption to less than a microWatt with three different termi-  
nation options.

The low power consumption and small packages of the  
DAC122S085 make it an excellent choice for use in battery  
operated equipment.  
The DAC122S085 is one of a family of pin compatible DACs,  
including the 8-bit DAC082S085 and the 10-bit DAC102S085.  
The DAC122S085 operates over the extended industrial tem-  
perature range of −40°C to +105°C.
