8-BIT ADC CHARACTERISTICS (Cont’d)
ADC Accuracy
Notes:
1. Negative injection disturbs the analog performance of the device. In particular, it induces leakage currents throughout
2. Data based on characterization results over the whole temperature range, monitored in production.

the device including the analog inputs. To avoid undesirable effects on the analog functions, care must be taken:
- Analog input pins must have a negative injection less than 1mA (assuming that the impedance of the analog voltage
is lower than the specified limits).
- Pure digital pins must have a negative injection less than 1mA. In addition, it is recommended to inject the current as
far as possible from the analog input pins.
