Hi, I am going to do A/D conversion with PIC12C672 @ IntRC (4MHz). Which one of the following cases will give me better accuracy: 1. Device in SLEEP (Int. ADC RC osc.) 2. Not in SLEEP, Int. ADC RC osc. 3. Not in SLEEP, 8Tosc Thanks. Arkady -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
