18 / 24 page  AD5306/AD5316/AD5326 Rev. F | Page 18 of 24 WRITE OPERATION When writing to the AD5306/AD5316/AD5326 DACs, the user must begin with an address byte (R/W = 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. This address byte is followed by the pointer byte, which is also acknowledged by the DAC. Two bytes of data are then written to the DAC, as shown in Figure 33. A stop condition follows. READ OPERATION When reading data back from the AD5306/AD5316/AD5326 DACs, the user begins with an address byte (R/W = 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. This address byte is usually followed by the pointer byte, which is also acknowledged by the DAC. Following this, there is a repeated start condition by the master, and the address is resent with R/W = 1. This is acknowledged by the DAC, indicating that it is prepared to transmit data. Two bytes of data are then read from the DAC, as shown in Figure 34. A stop condition follows.
