FWIW...I stay as far away from Maxim for any sort of
design that needs to be built in quantity.  You can
design a part in, find stock today but when you go (or
your CM) to order for a large build...if they don't
have stock, forget it.  They might get around to
building some parts later in the year.  For a company
that has so many cool parts, really a shame that they
get the reputation for this.  And I am talking about
10K annual so its not like just a few hundred.  Unless
you are using millions they just don't seem all that
interested.  Least thats my experiance with them.
