ADC CHARACTERISTICS (Cont’d)
ADC Accuracy with f
Figure 123. ADC Accuracy Characteristics
Notes:
1. Data based on characterization results, not tested in production. ADC Accuracy vs. Negative Injection Current: Inject-
ing 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
accuracy.
