Mechanical and electrical specifications

2.1
Table 3.
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. Self Test output changes with the power supply. “Self test output change” is defined as OUTPUT[LSb]
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
