Hello, reviewing the datasheet for the BMI160, it mentions in Page 12, under the block diagram that:
"The pre-filtered input data may be already temperature compensated or other low level correction operations may be applied to them."
Does this mean that the sensor data is already temperature calibrated on board the BMI160?
Solved! Go to Solution.
This simply means that ever part is trimmed at the factory, and that even the "raw" data or "pre-filtered" still has some pre-processing according to the trimming parameters on the ASIC. Then, it is filtered to the selected bandwidth.
All parameters of the datasheet reference this "pre-filtered" or the "filtered" data.

Thanks for your response and apologies for the delay in my own reply post.
What I was trying to understand is whether any additional temperature compensation is required for the accelerometer readings, as I am planning to use the BMI160 to measure vibrations in an environment where the temperature may vary between 15°C to 40°C. It's not clear to me from the datasheet whether this is required and what the basis for such a compensation calculation would be.
