Hi,I use ADC1_INP2 for single-end mode , how the ADC1_INN2 connect to?Internal VREF- or outside GND? And in differential mode,ADC1_INP6/ADC1_INN2 use de same pin, is that i can only use ADC1 channel 2 in differential mode? ADC1 channel 6 can't be used.
Solved! Go to Solution.

ADC1_INN2 is not used in single-ended mode. You can use it for something else, or leave it floating, or whatever.

Correct.
