1. Minimum and maximum values are based on characterization data and are not guaranteed

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 factory calibration test at socket level.

5. The sign of “Self-test output change” is defined by the ST bit in CTRL_REG4 (23h), 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 = 4 mg at 10-bit representation, ±2 g full scale

7. After enabling the ST bit, correct data is obtained after two samples (low-power mode / normal mode) or after eight samples

(high-resolution mode).
