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 ST bit, for all axes.
6.
“Self-test output change” is defined as the absolute value of:
OUTPUT[LSb]
(Self test enabled)
- OUTPUT[LSb]
(Self test disabled)
. 1LSb=4mg at 10bit representation, ±2 g Full-scale
7. After enabling ST, correct data is obtained after two samples (Low power mode / Normal mode) or after eight samples (high
resolution mode).
