10-BIT ADC CHARACTERISTICS (Cont’d)
12.12.3 ADC Accuracy
Conditions: V
Notes:
1. ADC Accuracy vs. Negative Injection Current: Injecting negative current may reduce the accuracy of the conversion
being performed on another analog input. The effect of negative injection current on robust pins is specified in
12.12.
Any positive injection current within the limits specified for I
accuracy.
2. Data based on characterization results, monitored in production to guarantee 99.73% within ± max value from -40°C
to 85°C ( ± 3σ distribution limits).
