Arduino Uno AREF

Post by ilovetoflyfpv »

Hi Gang

I'm trying use an Arduino Uno to read the RSSI voltage of a video receiver which varies between 0.5V and 1.15V. I'm thinking my simplest solution would be to use analogReference(INTERNAL); which is 1.1V to give me the best resolution. My concern is that I 'may' exceed the AREF voltage by 0.05V. Will this be a problem?

Cheers

Jase :)

I don't see anything in the datasheet warning against exceeding the aref voltage.
