HelloIn the IIS3DWB datasheet, it is said that the embeddeed temperature sensor offset can vary within a [-15°C : +15°C] range.Does that mean that the reading from OUT_TEMP_H/L can vary within [-256*15 LSB : +256*15 LSB] at 25°C ?Having tested 2 chip...

Understood, but is ST going to realease another acceleration sensor with 6kHz bandwith soon ?

In our application the IIS3DWB chip will be in close thermal contact with a massive rotating machine, and the chip will only be power supplied a minute every hour. So it should be ok, especially if we start the measurement cycle with the temperature....

Hello. You found the answer to your question about the ODR, you can not change it.It is fixed around 26.7kHz and may vary with temperature (±2%).It is not related to the way you setup internal filters.Hope it helps

Thank you, your answer helps.LIS2DTW12 is not suitable for our application, we need the DC to 6kHz bandwith. Any idea if there is something else in the pipe in this range ?

Thanks for your answer.The 2 chips I have tried are within 0.2°C (probably from a same lot), but I looked closer and their offsets are approximately -2.5°C, and I cannot afford that much.I think I was in denial, hopping for an error in the datasheet,...
