XTR116: Difference between XTR116U vs. XTR116UA

Part Number: XTR116

Hi Amps,

What is the difference between XTR116U and XTR116UA?
I did look at the datasheet and all of the electrical characteristics seems to be same, even the packaging info seems to be the same?


  • Hi Kris,

    The XTR116U has slightly better max offset and voltage accuracy specs (both room temp and drift) versus the UA version. See page 2 of the XTR116 datasheet.



  • Hi Jon, what is the distribution of these values around the nominal for UA? E.g. how likely is it to have values closer to maximum value? 

  • Hi Jones,

    for a customer the "individual fate" might also be decisive. In this case the maximum specification is important. And in this regard -according to the table above- the "U" is much better than the "UA".


  • Hi Jonas,

    The typical specs are not a guarantee, it's more an illustration of what you would expect to see from most of the parts and is not a tested spec. For a zero-mean spec like offset that can be positive or negative, the typical spec given is usually +/- 1 sigma. The max/min limits are the actual tested limits.

    In the case of the XTR116, the U version is subjected to higher screening than the UA part (tighter max specs). We cannot guarantee the distribution for any given UA part. Thus if a customer application requires the lower offset, they should choose the U part. As Kai said, it's important to go by the max spec in this case because that is the only guaranteed spec.
