... WRITE OPERATION When writing to the AD5629R/AD5669R, the user must begin with a start command followed by an address byte ( 0), after which the DAC acknowledges that it is prepared to receive data by pulling SDA low. The AD5629R/AD5669R require two bytes of data for the DAC and a command byte that controls various DAC functions ...
