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. The sign of “Self-test output change” is defined by CTRL_REG4 STsign bit
7. Self-test output changes with the power supply. “Self-test output change” is defined as
8. Output data reach 99% of final value after 1/ODR+ 1 ms when enabling self-test mode, due to device filtering
