What is the maximum voltage input value possible with the analog comparators on the AVR?
For example, is it possible to accurately compare voltage==+15.35 on the postitive AIN0 to voltage==+15 on AIN1 for the ATtiny45 without frying anything? What is the maximum voltage?
must the AIN0/AIN1 voltages be dropped to below 5v or internal reference w/ resistors?
thanks for any and all replies.
