Electrical characteristics
Table 60.
1. ADC DC accuracy values are measured after internal calibration.
2. ADC accuracy vs. negative injection current: injecting negative current on any of the standard (non-robust) analog input
3. Based on characterization, not tested in production.

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
accuracy.
