1. ADC DC accuracy values are measured after internal calibration.
2. Better performance could be achieved in restricted V
3. ADC accuracy vs. negative injection current: Injecting negative current on any of the standard (non-robust)
4. Preliminary values.

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 standard
analog pins which may potentially inject negative current.
Any positive injection current within the limits specified for I
affect the ADC accuracy.
