    Default What is the resolution of the analog comparator of the 16F628A?

    Hi,

    I would like to know the resolution the comparator channel. For example, using a PIC with A/D channel (10 bits) , the resolution is 4,88mV. I want to use a 16F628A, to compare 2 analog inputs. One with 3,100V and other with 3,115V for example...Is it possible or is necessary a minimal diference ?

    Thanks

    Resolution is infinite, or even bigger!
    There is no minimal difference, but you must count for input offset...
    It should be less then +-10mV(datasheet D300). You have 15mV, so not very good choose for your application.
