As Abishek says, it does appear that this part has Comparators, not converters.

Unfortunately, this just goes to show that you need to check the Data Sheet before placing orders - don't just rely on a feature list!
In other cases, you might find all those features listed, but certain restrictions mean that you can't use them all at once.

Of course, you can use a comparator to build and A-to-D...

Have you taken this up with Philips? The page is certainly misleading - whether intentionally or otherwise...
