1. ADC DC accuracy values are measured after internal calibration.
2. Better performance could be achieved in restricted VDD, frequency, VREF and temperature ranges.
3. Preliminary values.

ADC accuracy vs. negative injection current: Injecting a negative current on any analog
input pins should be avoided as this significantly reduces the accuracy of the conversion
being performed on another analog input. It is recommended to add a Schottky diode (pin to
ground) to analog pins which may potentially inject negative currents.
