B | Page 15 of 24 WRITE OPERATION When writing to the AD5301/AD5311/AD5321 DACs, the user must begin with an address byte, after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. This address byte is followed by the 16-bit word in the form of two control bytes. The write operations for the three DACs are shown in Figure 29 to Figure 31.
