Ah, I wondered why you were going though this driver with such a fine 
toothed comb!

The odd bit is it is already in the description... hmm. There is quite a 
disconnect between parts in the two
lists... Don't suppose you'd mind verifying this and cleaning up.  At 
somepoint the list of parts in here
is going to get two long.  Maybe it is already time to go to "AD5444 and 
similar SPI DACs"
and rely on the help to tell people what it supports.
