Mechanical and electrical specifications

Table 3.
1. The product is factory calibrated at 2.5V. The device can be used from 2.16V to 3.6V
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. If STM bit is used values change in sign for all axes
7. Self Test output changes with the power supply. Vst at 3.3V is typically in the range [-74; -7] LSb for X axis and [7;74] LSb for Y
8.
9. Output data reach 99% of final value after 3/ODR when enabling Self-Test mode due to device filtering
10. ODR is output data rate. Refer to
