WRITE OPERATION
When writing to the AD5110/AD5112/AD5114, the user
must begin with a start command followed by an address
byte (R/ W = 0), after which the
acknowledge that it is prepared to receive data by pulling
SDA low.
Two bytes of data are then written to the DAC, the most
significant byte, followed by the least significant byte. Both of

A repeated write function gives the user flexibility to update
the device a number of times after addressing the part only
once, as shown in Figure 44.
