1. ADC DC accuracy values are measured after internal calibration.
2. 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
