WRITE OPERATION
It is possible to write data for the RDAC register or the control
register. When writing to the AD5175, the user must begin with
a start command followed by an address byte (R/ W = 0), after
which the AD5175 acknowledges that it is prepared to receive
data by pulling SDA low.

Two bytes of data are then written to the RDAC, the most
significant byte followed by the least significant byte; both
of these data bytes are acknowledged by the AD5175. A stop
condition follows. The write operations for the AD5175 are
shown in Figure 25.
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 26.
