We have thermometers connected to AIN0 to AN2 as single-ended.
The full scale range of the ADC is 0 to 1.8V.
It's 1.8V on both VDDA_ADC and VREFP while VREFN is connected to VSSA_ADC on the board.
However it seems that ADC only gives us ~ 900mV full scale.
Could it be ADC input setting was at differential? Any suggestions? Thank you.
