As I recall, the maximum recommended input impedence for analog sources is
10k, according to the datasheets.  I'm sure higher impedances would require
longer acquisition times, but I'm NOT sure that there are no other problems.

I'd keep it around 5k to 10k just to be safe.  I'm sure someone with
"internal" knowledge of the PIC's construction will chime in and debunk
Microchip's recommendations, but I tend to stick by their datasheets just to
be safe.
