10-BIT ADC CHARACTERISTICS (Cont’d)
ADC Accuracy with 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 analog pins is specified in
12.14.
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 125°C (± 3σ distribution limits).
Figure 161. ADC Accuracy Characteristics
Notes:
1. ADC Accuracy vs. Negative Injection Current:
For I
for each 10KΩ increase of the external analog source impedance. This effect on the ADC accuracy has been observed
under worst-case conditions for injection:
- negative injection
- injection to an Input with analog capability, adjacent to the enabled Analog Input
- at 5V V
2. Data based on characterization results with T
3. Data based on characterization results over the whole temperature range, monitored in production.
