Hello Dave

The impedance in analog input in the PIC's is like maximun of 10 Kohms,
I have in my analog inputs a resistance of 4K7.

The maximun voltage is Vdd+0,6.

Ohhh, if you do a polling of the ADIF bit, for example, you don't
forggoten that you must charge the C of the sample & hold, and this time
is aproximadly of 10 microseconds. ;-))


Cheers
Santiago

MERRY CRHISTMAS Y VERY HAPPY NEW YEAR.
