I am wondering if routing a signal to an ADC input over one or several vias is an issue concerning precision of the measurement results. I always tried to avoid this the closer I come to the input the more, but I can't give a real reason why.
What is a vias equivalent circuit? Is there any influence on the signal at all?
My circuit deals with low frequency signals and I am using an ADuC847 with 24 bit ADC
Thanks for any answers.
