... 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 XRD54L08’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 ...
