Error on Application note (AN2834), AND Where to report it?

[Ass.1]

In application note AN2834 (How to get the best ADC accuracy in STM32 microcontrollers), There is a clear error on Page 10, which defines 1 LSB by Vref+/2^12). But LSB depends on Resolution!

If Resolution is 10, then it would be defined by Vref+/2^10.

Even Editor ownself was explaining a "10-bit resolution ADC" in previous pages(not a 12-bit one), So the reader would be confused by this. Writers should specify that "Vref+/2^12" specifies to "12-bit resolution".  

(Error reported here because There was no email or place to report AN errors.)

Hello @As.2s​ and welcome to the Community :)

Thanks for pointing out this issue.

I escalated your request to involved people to take the necessary action.

Hi @As.2s​ ,

Sorry for the delayed reply on this.

I confirm your remark, and it should be written as follow:

 The resolution in terms of voltage depends on the reference voltage. The error in terms of voltage is calculated by multiplying the number of LSBs by the voltage corresponding to 1 LSB = VREF+/2N or VDDA/2N for N-bit ADC.

This will be updated in the coming release of the AN2834.

Thanks

Thanks, Imen.

I completely agree with you on this update. I appreciate your work to improve application notes.

Thanks
