Need Information on ADXL356 Temperature Measurement Technique

Thank you for your post.  Perhaps you are looking for something more specific, but it would seem like the end of Table 1, on paqe 4 of the ADXL356's datasheet, provides some insight into this.  Does that help?

Hello again! Not sure if you are still working on this, but we have recently discovered an issue with this specification in the datasheet.   The output of the TEMP pin will be (nominally) 892.2mV at 0 degrees Celsius, not 25 degrees Celsius, as currently shown in the ADXL354 and ADXL356 datasheets.  I hope that this helps.

hello! thanks for your rely. I also found this problem that the temp pin is 990mV in office. the temperature will be approximately to 60℃ according to the datasheet. but the voltage will be change when the temperature changes. So it's work. I doubt something wrong in this datasheet and you confirm my doubt. Thank you!

You are welcome! We are glad that this was helpful.
