Hello,i am trying to understand the logic of the formula bellow. learned before the simple A2D formula resolution=amp/2^bits A2D_value=digitam_number*resolution

Is the some material i can read abou this formula?

Also is it correct the 2^scale/NUM_samples=duration?
We can't really tell without context. "Number-Of-Samples" implies that there is some kind of accumulation or averaging going on. "Scale" could be anything. 10*log(g) is how you convert a ratio, g, into decibels.
