1. Linear acceleration (LA), Angular Rate (AR) parameter labeling
2. Typical specifications are not guaranteed
3. Verified by wafer level test and measurement of initial offset and sensitivity
4. Sensitivity and zero-rate offset are not ratiometric to supply voltage
5. Typical zero-g level offset value after MSL3 preconditioning
6. Offset can be eliminated by enabling the built-in high-pass filter
7. Refer to Table 23 for filter cut-off frequency.
8. The product is capable of measuring angular rates extending from DC to the selected BW.
9. The sign of “Self-test output change” is defined by LA_CTRL_REG4 STsign bit (Table 27), for all axes.
10. Linear acceleration sensing Self-Test output changes with the power supply. “Self-test output change” is defined as
OUTPUT[LSb]_{(LA_CTRL_REG4 ST bit=1)} - OUTPUT[LSb]_{(LA_CTRL_REG4 ST bit=0)}. 1LSb=4g/4096 at 12bit representation, ±2 g
Full-scale
11. Output data reach 99% of final value after 1/ODR+1ms when enabling linear acceleration sensing self-test mode, due to
device filtering.
