Try also, the PIC 14000.  At a recent PIC seminar which I attended,
they stated it was designed for use with battery chargers and so the
A/D built-in was (relatively) slow but accurate.

I don't know if it's on-line.  Give Microchip a call.  They, and
their distributors, have been very helpfull and make information
easy to get.

Check a current Digi-Key catalog.  They're high priced, but do have
small quantities in hand for usually quick turn-around.  Don't know
if they're on-line, but they send new catalogs so frequently I would
expect you'd have a current one lying around.

Wait a minute -- from your .BR domain, I assume you're in Brazil.
