Hi Team,

Customer wants to know about DAC3171 layout.

Do we intend to leave a keep-out area in the thermal pad like below? Or it is okay to ground the entire thermal pad?

Thanks!

Hi,

It is ok to have the thermal pad on the board be the whole size of the thermal pad on the device. in fact, the released EVM does not cut back the pad on the board as it was shown in he example layout. I suspect that example layout was from an early EVM. Attached is the layout of the final EVM.

Regards,

Richard P.
