    That would require several books. I suggest you enroll in school where you can get those books and help to study them.

    The data sheet that you can find by using "icl7107" as a search term will give you much of that information. Then you can ask specific questions.

    I just happen to have a complete schematic of the meter I built some time back using a 7107. You do realize you will be spending about $300 and a hundred hours of time building a meter you could buy for about $50....

    Not to be immodest, but I souped the meter up pretty good. It's basic accuracy is about .05% DC, and I added a wideband AC signal process block to extend the usable AC bandwidth to about 150 kHz. I think it might be as good as a pretty decent $100 meter these days.....:D

    And if I allow myself $5/hour for all the time I spent fiddling with it, I probably only have about $500 in it. But it made me some money, as I recall some of the stuff I built for it got published in a magazine and I got paid for that...
