The analog signal is coming from a sample and hold op amp that is sampling an analog video signal coming from a CCD chip. Please click on the following link and look at the Vout signal on page 13 of the PDF. That is the signal we are getting before we attach the PIC chip.

Then when we attach it, the signal gets loaded down and all we get is noise in the A/D. thanks again for takin a look.
