ADC CHARACTERISTICS (Cont’d)
ADC Accuracy with V
Figure 92. ADC Accuracy Characteristics
Notes:
1. Data based on characterization results over the whole temperature range, monitored in production.
2. ADC Accuracy vs. Negative Injection Current:
For I
for each 10K
under worst-case conditions for injection:
- negative injection
- injection to an Input with analog capability, adjacent to the enabled Analog Input
- at 5V V
