    Hi everyone!
    I'm using the AD590 temperature sensor by analog devices (data sheet: The aim is to sense the temperature of a copper plate.

    Now I have one problem: The sensor (in flatpack package) has a ceramic side and gold plated side. Which one do I attach to the copper plate in order to get the best thermal connection?

    I would be very thankful for suggestions.

    hey sunseeker
    welcome to the forums :)

    thats a flamin' good question...
    well I was going to give the usual .... "did you read the data sheet" comment

    But after reading the datasheet and an application note sheet, I couldnt find anything definitive.
    And failing some one who knows for sure speaking up .... Im going with the gold side to the heat source. It seems the most logical
