Thank you all for your replies! I am just starting to learn more about analog design. As this is hardly a critical application, I will try going directly from the pots to the ADC. They are on a seperate board, so should I need to, I can always insert a buffer board in between. Any thoughts on if a .1uF ceramic cap would work in order to cancel AC error? (I happen to have a bunch of them) Is it better to place the cap nearer to the PIC or to the pot? Thanks again!
