1. ADC DC accuracy values are measured after internal calibration.  
2. Better performance could be achieved in restricted VDD, frequency and temperature ranges.  
3. Based on characterization, not tested in production.  
Note:  
ADC accuracy vs. negative injection current: Injecting a negative current on any of the  
standard (non-robust) 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 currents.  
Any positive injection current within the limits specified for I  
and ΣI

Section 5.3.12 does not affect the ADC accuracy.
