Injecting negative current on any of the analog input pins significantly reduces the accuracy of any conversion being
performed on any analog input.
Analog pins can be protected against negative injection by adding a Schottky diode (pin to ground). Injecting negative
current on digital input pins degrades ADC accuracy especially if performed on a pin close to the analog input pins.
Any positive injection current within the limits specified for I
accuracy.
