Use the 12-bit when you need accuracy more than speed, and use the 8-bit when you need speed over accuracy. It might help you come up with a need for the 12-bit A/D if you remember that even though the levels measured at an A/D should fall between the min and max reference levels, the initial source of what you are measuring may have been divided down or shifted to fit within those constraints. I could give several specific examples, but your question is vague and your e-mail is coming from a .edu address. I get the feeling that any answer more specific might be the answer to a class assignment. -Mike -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
