Re: A0 / ADC / TOUT value

Those numbers do look low. I normally see about +/- 5% in ADC from nominal across devices.
The voltage you quote is for theoretical voltages calculated from the divider ratio e.g.
5.23V (0.99619V on ADC)
Have you tried measuring the actual voltage on the ADC pin itself with a digital multimeter whilst taking the measurement. That would help eliminate any other reasons for the discrepancy.
