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.
a. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.71V to 3.6 V.
