ADC Characteristics
Note:
1. Gain error also depends on the accuracy of the selected reference source. When using VCC as a reference it should be
noted that the output voltage of the boost converter has a wide dynamic range, especially in Active Low Current Mode. The
internal voltage reference is rather immune to variations in supply voltage and is therefore the recommended reference
Table 20-8.
