    Hello,

    1. You can also look at the EVM User Guide for the ADS8688 for an example of PCB layout. Keep in mind that the TIDesign is designed to comply with IEC61000-4 Standards, if this is an aspect you are concerned with, I would suggest closely following the TIDesign layout.



    2. As for the RC, the RC used in the design is verified to work properly. The attached power point is a presentation that you may use to learn more about how to drive a SAR ADC input. It covers using an op amp and RC value selection.
