ADC accuracy characteristics
Table 44.
ADC accuracy(1) (2) (3)
1.
ADC DC accuracy values are measured after internal calibration.
2.
Better performance could be achieved in restricted VDD, frequency and temperature ranges.
3.
ADC Accuracy vs. Negative Injection Current: Injecting 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 current.
Any positive injection current within the limits specified for IINJ(PIN) and IINJ(PIN) in Section 5.3.12 does not
affect the ADC accuracy.
