Hi, I wanted to know if there would be a problem with having an input with a higher voltage than the Vref (ie 3.3v) in the analogue inputs as long as it is lower than 5 volts. I need to read an analogue sensor which can give any value from 0 to 5 but i only care for the range that is lower than 3v…

Analogue input when changing Vref

Thanks. Sorry, i guess i didn't find a better section for it. :~
