Temperature sensor on ISM330DLC

Hello, can you please tell if the temperature sensor on ISM330DLC returns absolute temperature values or the difference values with respect to a reference? Just read a thread (

https://community.st.com/0D50X00009XkXfjSAF

) that mentions 'difference with respect to a reference' so wanted to confirm if the same is happening for ISM330DLC as well.

Best regards,

Ankur

Here are the temperature sensor characteristics from the device datasheet.

As you can see the sensors measure difference values with respect to reference 25°C. The offset can be up to +/- 15°C.

Thanks Miroslav. So if we have multiple devices with this sensor, every device can have a different temperature offset, correct?

Yes, it is correct.
