Custom NI USB-6363 Breakout Board - Best practices?

[Jimbles]

Hey,

I am designing a custom breakout board for the NI USB-6363 and I had some questions about best practices 

Should I have a AGND plane? 

Should I connect all AGND pins together or only use one? 

Thanks very much for any advice you can offer!

Cheers,

Jimbles

Hi Jimbles,

-Yes

-And yes. NI 6363 comes with several AI GND pins for convenience however they're all in the same plane.
