a. The ADC reference voltage is 3.0 V. This reference voltage is internally generated from the 3.3 VDDA supply by a band
gap circuit.
b. The ADC must be clocked from the PLL or directly from an external clock source to operate properly.
c. The conversion time and rate scale from the specified number if the ADC internal clock frequency is any value other than
16 MHz.
d. The offset error listed above is the conversion result with 0 V applied to the ADC input.
