C WRITE OPERATION
There are three specific modes in which data can be written to
the AD539x family of DACs.
Rev. A | Page 28 of 44
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 pre-
pared 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 then are 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.
