You have to state your criteria for assessment first. You cannot simply say " I want to assess the quality." You can say it but it is meaningless as far as any engineering or scientifice analysis is concerned. You have to say " I want to assess the quality for an accuracy within such and such range. If you know what you are asking then you must know you need an A to D . Look at the linked datasheet (by a real company) . State the criteria. Define your terms. "Quality" is not a quantitative word so I don't know how you plan to assess "qualiity" if you don't know what you are looling for. When you can state that , we can tell you how to look for it.
Do you plan to look at the data and say "Oh, ok, that looks ok.." ? Do you see my point ? "Quality" doesn't tell us much. Do you know what you are looking for ? Are you a doctor or and engineer or scientist ? How do you know when the signal is good enough ?
You haven't even stated what resolution of measurement you are looking for (8 bit,16 bit etc...)
