1. ADC DC accuracy values are measured after internal calibration.
2. Better performance could be achieved in restricted V
3. Based on characterization, not tested in production.
ADC accuracy vs. negative injection current: Injecting a 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 currents.
Any positive injection current within the limits specified for I
