... DAC is not daisy-chained then only a 12 bit serial word is needed to program the DAC. The next bits after the 4 leading bits are data bits. The XRD5408’s first 8 bits are valid data and the trailing 4 bits must be set to 0. Figure 7 demonstrates the 16 bit digital word for the 8, 10,12 bit DACs ...

... The XRD5408/10/12 family of DACs are monotonic over the entire temperature range. Micro-Power Operation The XRD5408 is the lowest power in their class. The quiescent current rating does not include the reference ladder current. Power can be saved when the part is not in use by setting the DAC code to all “0”s assuming the output load is referenced to ground ...
