    Default Find the right PIC...

    Hello,

    I just toasted my last 16F88...

    This PIC has ADC "Vref+" and "Vref-" ability.

    I was looking for some replacement PIC having the same feature in the MICROCHIP's web site.

    Unfortunately, this feature is not listed (or I can't see it) in the selection table so I need to look at every and each datasheet; this can take a long long time!

    Does anyone know how to find this information quickly?

    Thank you.
    Roger

    also try the 18F1320 ... which is also 16F88 compatible !!!

    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 " !!!

    Coooooooooooooooooooooooooool !

    Will need to get a faster internet connection then

    Merci encore.

    BTW, do I understand the datasheets well if, in the case of the "Vref+" and "Vref-" use, "Vref+" can not be higher than Vdd and "Vref-" can not be lower than Vss? Or does "Vref+" and "Vref-" accept any voltage as long as their voltage difference doesn't exceed 5V?

    Each Vref have to be >0 and <Vdd

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