Figure 4. LDAC-Controlled Update Using 8-Bit Serial Word
Table 2 lists the A1 and A0 bits and the selection of the updated DACs. The RNG bit controls the DAC output
range. When RNG = low, the output range is between the applied reference voltage and GND, and when
RNG = high, the range is between twice the applied reference voltage and GND.
