Part Number: TMP117

In the datasheet, the exposed pad isn't shown in the recommended land pattern, it's a typo?

Thanks.

Dear Diverger -

Please see page 41 or 44 in the datasheet, depending on which package variant you are asking about ==> https://www.ti.com/lit/ds/symlink/tmp117.pdf

I mean the DRV version. In page 41, the recommended land pattern has no exposed pad..

Dear diverger -

On page 41, the exposed metal is annotated in three places.

I mean the EP under the chip. The EP pad is not shown.

Hi diverger,

We recommend that the exposed pad not be soldered due to stress and accuracy concerns.

thanks,
