STM32G0/L4/etc. ADC "CALFACT" is obviously some calibration factor, but how do you translate the 7 bits into a numerical value that multiplies the result? Reference manual does not seem to want to say.

It is used internally by the ADC during conversion, i.e. you don't use it to modify the conversion result.

It is used internally during a conversion and is some sort of multiplication factor. What I am after is how to translate the CALFACT number into the actual amount results are multiplied by.

That's not documented.

You may be mistaken in considering it to be a multiplier.

Why can't you use the ADC as intended and as described?
