HTCC-AB02 ADC Resolution (Max 2.4V 12bit)?

Hi, I read the document said the input maximum voltage of ADC is 2.4V, and 12 bit ADC resolution should be 4096.

I input 2.4 v into ADC2, but the result AnalogRead(ADC2) is 2400, anyone could help??

Is your development environment up to date? If it is not, then the value returned by AnalogRead() should be mV. In the latest development environment, the value returned by AnalogRead() is 0-4095, and the value returned by analogReadmV() is mV.
