Note:

ADC accuracy vs. negative injection current: injecting a negative current on any 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 analog pins which may potentially inject negative currents.

Any positive injection current within the limits specified for IINJ(PIN) and ∑IINJ(PIN) in

Section 6.2 does not affect the ADC accuracy.
