https://devzone.nordicsemi.com/f/nordic-q-a/41641/temperature-accuracy-and-piece-wise-linear-termsThe temp accuracy is stated at +/-5C. Does that include using piece-wise linear terms for accuracy? Is there any data on accuracy over a narrow temp range such as 0-40C?

Likely in the &lt;+/-1.5C range. Typically it is at the higher temperatures (&gt;40C) that you will see the most deviation, though it seems to consistency measure too high at the higher level, so if you subtract with 1-2C when passing 40C you should improve accuracy.</p><div style="clear:both;"></div>
