Note: 1. These parameters are hypothetical (not tested) and are provided for design reference use only.
2. There is no current consumption when ADC is off other than minor leakage current.
3. AD conversion result will not decrease when an increase of input voltage and no missing code will result.
4. These parameters are subject to change without further notice.
