Can the selected channels to ADC0, ADC1 and ADC2 in STM32H753ZI be sampled simultaneously under the same sampling clock?

[RongShengWang]

Hi,

1. Can the selected input channels to ADC0, ADC1 and ADC2 in STM32H753ZI be sampled simultaneously under the same sampling clock?

2. NUCLEO-H753ZI ADC does not accept the analog negative signal inputs. Is there any STM32H7 dev board(s) accepting the analog negative signal inputs?

   Thanks,
