1. Min/Max values are based on characterization results, not tested in production and not guaranteed.

2. Typical specifications are not guaranteed.

3. Sensor is designed with larger dynamic to avoid variation of FS limits in the operative bandwidth.

Consequently to trim operations at factory final test.

4. Sensitivity range after MSL3 preconditioning.

5. Typical zero-g level offset value after MSL3 preconditioning.

6. Valid if OFF_TCOMP_EN in CTRL_REG4 (23h) is set to '1'. Min/max at 3 sigma. Based on characterization

data for a limited number of samples, not measured during final test for production.
