Notes:
1. Unless otherwise specified, typical data is based on T
lines and are not tested.
2. When V
3. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10kΩ). Data
based on characterization results, not tested in production.
4. The stabilization time of the AD converter is masked by the first t
