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. Accelerometer “Self-test positive difference” is defined as: OUTPUT[mg]_{(CTRL_REG5_A ST2, ST1 bits=01)} -
OUTPUT[mg]_{(CTRL_REG5_A ST2, ST1 bits=00)}.
6. Magnetic “self-test” is defined as: OUTPUT[gauss]_{(CTRL_REG1_M ST bit=1)} - OUTPUT[gauss]_{(CTRL_REG1_M ST bit=0)}.
a. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.9 V to 3.6 V.
