ADC CHARACTERISTICS (Cont’d)
ADC Accuracy with 3V
ADC Accuracy with 4.5V
Notes:
1. Data based on characterization results over the whole temperature range, monitored in production.
2. ADC accuracy vs negative injection current: Injecting negative current on any of the analog input pins 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
Any positive injection current within the limits specified for I
accuracy.
3. Data based on characterization results, monitored in production to guarantee 99.73% within ± max value from -40°C
to +125°C (± 3σ distribution limits).
