vias in high resolution ADC layouts

Hi,

 

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.

 

Martin
