AD5337/AD5338/AD5339
Multiple-DAC Read Back Sequence.
If the user attempts to read back data from more than one DAC
at a time, the part reads back the default, power-on reset
conditions, i.e., all 0s except for CLR, which is 1.
Rev. A | Page 17 of 24
WRITE OPERATION
When writing to the AD5337/AD5338/AD5339 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.
