Instead of using a A/D, you could always use a comparator to an input on one of the port pins. You could have a routine that loops and stores the state of the pin into a bit in memory. Once you have eight of these you have a byte from 0 to 255. I imagine the actual value would linger somewhere in the middle, but thats expected for guassian type noise.

I guess you could use, if applicable, a built in comparator, but you should turn Interrupts for it off.
