    Any idea of the time range between both voltage?

    Looks like a kind of ESR measurement to me

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Ok so in theory, you shouldn't have any problem with a 16Bits timer. BUT you'll need to compensate for the ADC sampling time.

    What you could also do is to use a comparator interrupt...
