DAC REGISTER
The DAC register is addressed by setting the three REG bits to 000. The DAC address bits select the DAC channel which the data transfer
is to take place (see Table 18). The data bits are in positions DB15 to DB0 for the AD5754R (see Table 19), DB15 to DB2 for the AD5734R
(see Table 20), and DB15 to DB4 for the AD5724R (see Table 21).

OUTPUT RANGE SELECT REGISTER
The output range select register is addressed by setting the three REG bits to 001. The DAC address bits select the DAC channel, while the
range bits (R2, R1, R0) select the required output range (see Table 22 and Table 23).
