1. Typical specifications are not guaranteed.

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

operations at factory final test.

3. Sensitivity range after MSL3 preconditioning.

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

5. Min/max at 3 sigma. Based on characterization data for a limited number of samples, not measured during final test for

production.

6. Self-test positive difference is defined as:

OUTPUT[mg](CTRL_REG4 (23h) ST2, ST1 bits = 01 ) - OUTPUT[mg](CTRL_REG4 (23h) ST2, ST1 bits = 00 ) in steady state.
