IT8705F Data Sheet and Help

See figure 10-4 and the following formulas in the 8705 and 8712
datasheets.
The 8705 datasheet I have has the wrong formula, the 8712 is right.
You need to know Rin, Rf, and Vref to compute the correct formula.
Unfortunately, since the datasheet doesn't give the board designer a
recommendation, you will have to find and measure the values on
your board.

I'll put the formulas in sensors.conf.eg so others can find it.
