AD8000&AD8001 PCB design issues

Hello,

I'm designing AD8000&AD8001 for testing purpose. The AD8000's datasheet says:"Do not use ground and power planes under any of the pins of the AD8000." Is this means that I have avoid copper of the ground (or power) plane adjacent top layer? 

Below is my baord's layers structure:(Do i have to remove some copper of the Agnd1 just under the AD8000&AD8001?)

And here is the AD8001 and AD8000 used in my new test board:

Anybody can show me an example of this?

    Hi.

    I don't think the removal of ground plane in the input and output pins was implemented in the EVAL-HSOPAMP-1CPZ which is primarily used as the evaluation board of AD8000. Anyhow, you can refer to the attached file. It contains all the board files of EVAL-HSOPAMP-1CPZ. You can see the layout files under 20_041825a-->worklib-->02_041825a_top-->physical-->art-->fab. It was created from Allegro.

    I'll look for the board files of AD8001 evala board and will get back to you on this.

    I also recommend you to purchase the evaluation boards so you don't have to make your own boards. It would be easier for you to just setup the board then test it.

    Regards,
