@All.
Why you are multiply by 1000. It is not necessary;
10/2^12-1 = 2.44mv.
Formula =E(v)/2^n-1 (n=no of bits).

Formula used : R=V/(2^n)-1.
Where R= resolution.
V=voltage.
N =bit used.
Where R= resolution.
V=voltage.
N =bit used.

But, the answer should be in the form of mV that's why he multplyed by 1000.

10/(2^12 - 1) is 0.002442.
When you multiply with 1000 we get 2.442? How come it is 2.44m?
