1.
The product is factory calibrated at 2.5 V. The device can be used 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.
If STM bit is used, values change in sign for all axes.
6.
Self Test output changes with the power supply. “Self Test Output Change” is defined as OUTPUT[LSb](Self-test bit on ctrl_reg1=1)
-OUTPUT[LSb](Self-test bit on ctrl_reg1=0). 1LSb=4.6g/256 at 8bit representation, ±2.3g full-scale.
7.
Output data reach 99% of final value after 3/ODR when enabling self-test mode due to device filtering.
8.
ODR is Output Data Rate. Refer to
Table 4 for specifications.
