F3/L4 ADC in Differential mode.

Hi,

 

When  two inputs of ADC are in differential mode, can the ADCxINN input voltage be higher than the ADCxINP input voltage?

For Vref+ = 3.3V and Verf- = 0V.

Is the result value =  ((ADCxINP - ADCxINN)/3.3) * 2048 + 2048?

Ex. If ADCxINP = 1.0V and ADCxINN = 2.65V, is the result value = 1024?

 

Ari.
