Hello

Could you please tell me the input volatage range (Min ~ Max) of the ADC.Will the value of Min/Macx of VREF_ADC1(VDDDmin ~VDDDmax) be applied as it is?

Best Regards

Arai/Macnica

Hi Rajath

Is it ok to think that MAX ADC input voltage is 3.65V and MIN ADC input voltage is 3.15V when VBUS powered?Because  VDDIO is shorted with VDDD.

Just in CASE, Considering the ADC input voltage, MIN. input voltage is 0V, and MAX input voltage is  ( 3.15v ~ 3.65v)。

Is it correct?
