    Dear Fred - 

    Thanks for the post! Here you will need to give us a bit more detail about your problem as this part is ±0.15C accurate in that temperature range. 

    I would suggest you share details that you can on the schematic, the layout and even the code snippet from you converting the output of the device to C, then we should be able to quickly get back to you will helpful suggestions towards resolution of your problem.
