Module specifications
Table 3.
1. Typical specifications are not guaranteed
2. Verified by wafer level test and measurement of initial offset and sensitivity
3. Typical zero-g level offset value after MSL3 preconditioning
4. Offset can be eliminated by enabling the built-in high-pass filter
5. The sign of “Self-test output change” is defined by the CTRL_REG4 STsign bit
6. Self-test output changes with the power supply. “Self-test output change” is defined as
7. Output data reach 99% of final value after 1/ODR+1ms when enabling self-test mode, due to device filtering
