What is the difference between ADS1252 & ADS1252U? What is the meaning of 'U'?

Anyone can answer me the question?

Thanks.

    Hi Leo,

    I couldn't find any documentation indicating the significance of the "U". Typically, our part numbers end in "I + <package #> + <T/R> (tape or reel)". Sometimes you will see other letters or numbers which have to do will lead-free packaging.

    There is no difference between the ADS1252 and the ADS1252U. If you notice from the "sample and buy table", all of the ADS1252 devices are given the part number ADS1252U...

    If you need more information about the "U" I can see if I can find a contact in TI who might know more about this.

    Best regards,
    Chris

    Leo/Chris,

    The 'U' refers to the old part numbering system for Burr-Brown and means the part is packaged as SOIC.
