the snubber circuit on the internal DC/DC regulator

Hello,

To improve the performance of SAADC, I would like to isolate the SAADC from the bad effect of DC/DC and RF.

I assume that SAADC has some noise because of DC/DC operation.

Could I add the snubber circuits between the terminal "DCC" and GND?

Any problem?

If you have other effective solutions, let me know them, please.

Best regards,

Kiyoshi Iwai
