I don't understand the following about the ADA4945-1:
From page 42 of the datasheet (rev 0.):
If the common mode voltage is set to 2.5V, wouldn't the output swing from 0.5V to 4.5V, and not from 0V to 4V like it's mentioned in the excerpt above?

Hi,
We are currently looking into this. We'll keep you posted.

Hi Dan,
Thanks for pointing this out!
I agree that the swing should be 0.5V to 4.5V – this seems to be a mistake in the datasheet.
I’ll add the “0V to 4V” swing to the list of items to correct in our datasheet revision.
