There is very little information in the datasheet about the driving capability of digital I/O pins. I am using the AD7768 in daisy-chain configuration and the question came up about the driving capability of the DOUTx pins.
Since these outputs drive the line to the input of the next device in the chain at about 10MHz they must be able to supply some current. Is there any additional info on this?
What about the other digital pins like the GPIOs?
