Hi Natalia,
if all you wanted is to use the part in Eagle you can download the ".bxl" file from our website
http://www.ti.com/product/TMP112/quality
And use the free software "Ultra Librarian" (link also in the webpage above) to convert it to any program you need.
I did this for you and attached the Eagle library file ".lbr" for the TMP112 to this post.
Hope this helped!
Best Regards,
Simon
