STM32H725VGH6 interleaved mode

[shaktipg]

Hi! I am using STM32H725VGH6 series MCU, in the datasheet it is clearly mentioned that it has 2 direct 16bit ADC channels, while it is not there when trying to configure in STM32CubeIDE. Can you make sure the datasheet is correct or not?

Have you seen if this post helps in the case?

This became helpful for understanding the interleaved mode configuration of mcu, but here I want configure as differential (not single ended),  interleaved mode using direct channel ADCs so that it can be achieved high sampling rate. So please help me! And also take care of my previous question.

I found this information, check if it's your case:

Caution: When configuring the channel “i” in differential input mode, its negative input voltage is connected to V INN[i]. As a consequence, channel “i+n”, which is connected to VINN[i] , should not be converted at same time by different ADCs. Some channels are shared between ADC1/ADC2: this can make the channel on the other ADC unusable.

Can you please go to my main question mentioned below-

2x 16 bits ADC + 1x 12 bits ADC:

Note: The version I'm using is 1.12.1, so maybe there might be a bug if it's not appearing like this in version 1.13, in which case it's better to open a new question.

Hello @shaktipg ,

Could you explain what do you mean by "while it is not there "

Thanks

Here I've attached a snapshot (datasheet STM32H725xE/G, page n. 20), mentioned number of direct channels ADC1/ADC2 is 2. Can you please confirm me the MCU pins (pin number/name which can be configured for these channels) for these channels?
