Dear friends,I'm setting a differential ADC input for my application.The Positive voltage connects to ADC1_IN1 and the Negative connects to ADC1_IN2.When I reading the 0V, the result I get is 1583 values of ADC (It is the raw data, I did not convert ...

Hi Uwe Bonnes,The 1583 is the ADC value at the 0V differential voltage ADC input, and I didn't set the VREF. VDD is 3.3V.I used a small package of STM32F303, so have no VREF pin.And I read the Vref by ADC then the value is 1409, with the CALFACT_S va...
