Hi, I'm using multi channels ADC3 of "STM32H735ZGT6" (3channels)
I want to use these channels in parallel, but I've only found a way to convert in order in the Datasheet.
Can I run all the ADC3's channels at once in parallel?
If that is the case, can I get a reference manual or some advice?
If you want to see my CUBEMX or Code, Please tell me.
Thank you.

Hello @giwonKIM,
ADC3 (in addition ADC1/2) does not allow parallel conversion.
You can only configure a sequence of channel rank to chain them. Or, if you absolutely need to convert them in parallel, use 1 ADC per channel.
I hope it answers to your question.
Kind regards,

I organized 3 channels of ADC3 like this picture.
As you said, do you mean you can't convert 3 channels (IN0,IN1,IN10) at the same time and can do it in order?
If so, should we use each channel of 3 ADC blocks (ADC1, ADC2, ADC3) as shown in the picture below to convert at the same time?
