Are we actually saying here that by using higher attenuations, we can apply higher input voltages? I had always assumed that applying more than 3.3V as input to a pin would "fry" the device. Are special precautions needed here? For example, if one is working with a 10V potential input, if one "mis-wired" on their breadboard ... do we damage something? If I make a programming error and specify no attenuation but apply 10V on the ADC input pin, will that damage something?
All thoughts on this area of ADC very welcome.
