Please tell us about the recommended pattern design and layout design of the ADA4870.

Hi, I would like to use ADA4870.

So, I have a question. Please help me.


I am concerned about the heat dissipation design when considering the ADA4870.

I saw the recommended land information of the manufacturer.

The heat dissipation land is rectangular,
A hatched part with no dimensional description pops out at the left and right ends,
It is drawn as if to set a forbidden zone (yellow box in the figure).

However, on the data sheet, there are contacts in this part,
Copper foil is also drawn in the recommended pattern drawings.

In this part too,
set the radiation land in the same shape as the contact point on the back side,
Is it OK to provide resist openings and metal openings?

Best regards,
