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
Any positive injection current within the limits specified for I
affect the ADC accuracy.

In this type of ADC, calibration is necessary to correct
gain error and offset errors. Once calibrated, the TUE is
limited to the ILE.
