1.

The product is factory calibrated at 2.5 V. The operational power supply range is from 2.16 V to 3.6 V.

2.

Typical specifications are not guaranteed

3.

Verified by wafer level test and measurement of initial offset and sensitivity

4.

Typical zero-g level offset value after MSL3 preconditioning

5.

Offset can be eliminated by enabling the built-in high pass filter

6.

If STM bit is used values change in sign for all axes

7.

8.

Output data reach 99% of final value after 3/ODR when enabling Self-Test mode due to device filtering

9.

ODR is output data rate. Refer to Table 4 for specifications
