DAC REGISTER

The DAC register is addressed by setting the three REG bits to 000. The DAC address bits select the DAC channel in which the data

transfer is to take place (see Table 17). The data bits are in positions DB15 to DB0 for the AD5752 (see Table 18), DB15 to DB2 for the

AD5732 (see Table 19), and DB15 to DB4 for the AD5722 (see Table 20).

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, and the

range bits (R2, R1, R0) select the required output range (see Table 21 and Table 22).
