POT jitter on ADC???

[Batz Goodfortune]

Y-ellow y'all.
	The question: If I stuck a suitably sized cap across the wiper of a POT
and ground, which feeds the input to an A-D converter, would it...
(a) Stop the occasional jitter from the pot?
(b) Cause damage to the input of the A-D on power up/down?

The problem: I have an A-D converter reading a POT. That's all it has to
do. It works OK but occasionally the pot positions it self where it
jitters. Like it's a switch bouncing. It reeks havoc sometimes. Especially
on bootup. I was thinking that maybe a cap on the input of the A-D with a
small series resistor from the wiper of the pot might do the trick. But
then I thought that the charge on the cap might fry the input as the
voltage falls on power down. Taking the input beyond it's safe operating area.

I thought that maybe if I also placed a pair of diodes across the input,
Cathodes pointing up to Vcc might protect it? 

Anyone have experience with this kind of thing?

Thanks in advance.
