How to choice the best pin for ADC input?

[Vyacheslav Azarov]

Hello everyone,

How to choice the best pin for ADC input, with lowest noise or/and serial resistance?

Thanks.

the one that you can make work is the best pin.

Your analog circuitry at the pin, and the stability of VDDA/VREF, will have the greatest impact.

Thanks for all. However, I was referring to internal cross-talking with digital circuits, what leads to increase the noise. Or this effect does not occur?
