MHz
(1) Connect adc_vrefp to vdda_adc when not using a positive external reference voltage.
(2) This parameter is valid when the respective AIN terminal is configured to operate as a general-purpose ADC input.
(3) The maximum sample rate assumes a conversion time of 13 ADC clock cycles with the acquisition time configured for the minimum of 2
ADC clock cycles, where it takes a total of 15 ADC clock cycles to sample the analog input and convert it to a positive binary weighted
digital value.
