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 (
Table 27), for all axes.
7.
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=12g/4096 at 12bit representation, ±6 g Full-
scale
8.
Output data reach 99% of final value after 1/ODR+1ms when enabling self-test mode, due to device filtering
Hz
