Table 50.
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)
3. Based on characterization, not tested in production.

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.
