I'm trying to understand the following section of the Arduino Uno's schematic:
The Arduino's site recommends that Vin should be between 7 and 12V. However, I was reading the datasheet for the comparator (LM358) and it seems that the voltage range is -0.2 to 5.7V, where 5.7V is absolute maximum for the input pin.
As a result, wouldn't 12V damage the chip since 12V would input 6V into the comparator?
I tried asking this question in another forum. However, no one really knew the answer why, and tech support at SparkFun was also stumped.
Thanks for the help in advance!
