1. Data based on characterization results, not tested in production. 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. The effect of negative injection current on robust pins is specified in
pin characteristics.
Any positive injection current within the limits specified for I
pin characteristics
2. Under characterization.
