0693W000008xSTkQAM.pngIn RM0440, STM32G491 is Category 4.

Therefore OPAMP6 can be connected to ADC3 refer to RM0440 21.4.4(ADC Connectivity)

But I cannot find check option for OPAMP6 in ADC3 setting.

Is it unavailable? or not implemented yet?

Hello @yjsbd​ 

Thank you for your feedback,

I have checked on my side and yes, you're totally right, there's an issue in CubeMX regarding the OPAMP6 connectivity with ADC3, a VOPAMP6 Channel is missed under ADC3.

Thanks for raising this issue to our attention :) it will be fixed.
