I2C WRITE OPERATION
There are three specific modes in which data can be written to
the AD539x family of DACs.
4-BYTE MODE
When writing to the AD539x DACs, begin with an address byte
(R/W = 0), after which the DAC acknowledges that it is prepared
to receive data by pulling SDA low. The address byte is followed
by the pointer byte. This addresses the specific channel in the
DAC to be addressed and is also acknowledged by the DAC.
Address Bits A3 to A0 address all channels on the AD5390/
AD5391. Address Bits A2 to A0 address all channels on the
AD5392. Address Bit A3 is a zero on the AD5392. Two bytes
of data are then written to the DAC, as shown in Figure 33.
A STOP condition follows. This lets the user update a single
channel within the AD539x at any time and requires four bytes
of data to be transferred from the master.
