Hi Tech,

part#THS4561DGKEVM

The utilized IC on physical board shows "4551" marking, NOT matched with spec shown THS4561 IC.

The image on TI's website also appears "4551".

Could you help check and clarify?

Thanks.

Hi Jun,

Just to confirm did you directly see these 4551 markings on a THS4561DGKEVM you received? Or is only an observation made when looking at the image on the product page?

Best Regards,

Ignacio

Hi Jun,

We were able to order the same EVM and received the correct device. Just to confirm, did you receive the THS4561EVM with the THS4551 device?

Best Regards,

Ignacio

Hi Ignacio,

Yes, the customer received THS4561DGKEVM but with the THS4551 device. I just want to confirm if it is normal phenomenon?

Thanks.

Hi Jun,

This is not normal and was a mistake on our end if the customer received this through us. I sent a friend request so we can discuss steps we can take to correct this for you.

Best Regards,

Ignacio
