(1) Load current on VREFHI increases when ADC input is greater than VDDA. This causes inaccurate conversions.
(2) A ceramic capacitor with package size of 0805 or smaller is preferred. Up to ±20% tolerance is acceptable.  In external reference mode, capacitance is dependent on reference IC buffer output requirement.
(3) IO activity is minimized on pins adjacent to ADC input and VREFHI pins as part of best practices to reduce capacitive coupling and crosstalk.
(4) Variation across all channels belonging to the same ADC module.
(5) Worst case variation compared to other ADC modules.
