Sure, no problem.
There is a typo in Equation 11... the correct equation for the output code should be:
If you want to plot your ADCout data in terms of volts, you would have to solve the previous equation for the "Vinp-Vinm" term. Keep in mind that the equation already takes into account the gain of the amplifier, so "Vinp-Vinm" is the differential voltage at the input of the chip.
I hope to have answered your question. If now, please let me know and we can continue the discussion.
