Those are really old charts! Over 10 years old (revision 2008) a lot has changed since, introduction of CDFA non-precision approaches, PBN, RNP approaches etc. RNAV has become more important, conventional arrivals have largely disappeared etc.
These are the most recent ones, you can see the vertical profile has been completely revised. The minima remained the same, which really is a MDA still instead of a DA, so you have to add a correction to these minima to use them as a DA.
