IIS3DWB temperature sensor offset

[pb38]

Hello
In 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 chips myself, I got a much better result.
I am then wondering whether I was just lucky, and if I really need to calibrate.
Thanks

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.
We may go to an OPC using a more accurate sensor that we have somewhere else in the product's shell.  Obviously this other sensor is not in close thermal contact with the monitored machine (otherwise we would use it instead), so we will have to process the OPC when the temperature is stabilized.

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

They probably don't because installation on a PCB causes additional bias that they have no control over.
