How to select gain in STM32H743 ADC? I looked up all the configurations/parameters but don't see how can I amplify (select gain) for input channel? I want to measure current which is mV signal.

Correct, there is no built-in amplifier.

Welcome, @NVerm.2, to the community!

If you want to measure something in the millivolt range, you have to connect an amplifier stage in front of the ADC input.

Does it answer your question?

Hi Peter,

Yes, thanks, it means it does not have amplifier built-in where I can select gain x.
