Having some trouble with a fully-differential signal driven directly into STM32F303 setup for differential mode. There is an errata about common-mode voltage having to be within 10% of center which may or may not apply. Does ST consider the common-mode to be the average of the two signals -- which is always centered? Or do they use the term to simply be the voltage you present to the negative ADC input? (Would appreciate knowledge-based answer rather than options based on general knowledge and reading the datasheet)
