    Wink Zener ???

    Hi, Adam

    I Think zener thresold changes too much with temp ( slope depends on the zener voltage... )

    a test with a TL 431 should give some usable results.

    Now, it would be simpler to tell us what's you've in mind ... just thinking a lead acid ( or else !!! ) batt. voltage is a non-negligible function of the ambiant temp ... ( around 20 mv/°C and cell ... from oooooooold my memory )

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
