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 CTRL_REG4 STsign bit, for all axes.
6.
Self-test output changes with the power supply. “Self-test output change” is defined as
OUTPUT[LSb]
(CTRL_REG4 ST bit=1)
- OUTPUT[LSb]
(CTRL_REG4 ST bit=0)
. 1LSb=1mg, ±2 g Full-scale.
7. Output data reach 99% of final value after 1 ms when enabling self-test mode, due to device filtering.
