16.15 10-BIT ADC CHARACTERISTICS
Operating Conditions: V
Notes:
1. Data by design. They are given only as design guidelines and are not tested.
2. When V
Channel 0 cannot be used because AIN0 pin is the Input for V
3. Any added external serial resistor will downgrade the ADC accuracy. Data by design, not tested in production.
4. Approximated value corresponding to about 20 conversion cycles, that is recommended at A/D start-up to ensure a
correct conversion.
Table 16.18 ADC Accuracy with V
Notes:
1. Data based on characterization results over the whole temperature range, monitored in production.
