Hi,

 

I am looking at data sheet but I am not sure about the data width of ad7609 for SPI.

 

The configuration :

  1. Serial interface mode
  2. only use DoutA
  3. I believe Polarity=1 and Phase=0
  4. 100Khz clock rate
  5. what is data width??

 

In parallel mode, it seems to be 16bits, but in case of serial mode i am not sure whether it is 16 bits or 18 bits

 

Regards,

Jin
