1. Min/Max values are based on characterization results at 3σ on a limited number of samples, not tested in production and not guaranteed.

2. Typical specifications are not guaranteed.

3. Sensitivity values after factory calibration test and trimming.

4. Value after calibration.

5. Measurements are performed in a uniform temperature setup and they are based on characterization data in a limited number of samples.

Not measured during final test for production.

6. Gyroscope rate noise density in high-performance mode is independent of the ODR and FS setting. Gyroscope noise density is computed

starting from measured noise RMS and considering BW = ODR/2.

7. Gyroscope RMS noise in low-power mode is independent of the ODR and FS setting.

8. Accelerometer noise density in high-performance mode is independent of the selected ODR and FS. Accelerometer noise density is

computed starting from measured noise RMS and considering BW = ODR/2.

9. Noise density is between 10 Hz and 1 kHz.
