1. Typical specifications are not guaranteed.

2. Values after factory calibration test and trimming at T = 25 °C.

3. Long term includes the following conditions: post solder, drift in temperature in the range [-40°C to +105 °C] and over life.

4. Max. values from design and characterization at ambient temperature (T = 25 °C).

5. RMS noise is the same for all ODRs.

6. Noise density is the same for all ODRs.

7. Based on characterization data on a limited number of samples. Not measured during final test for production.

8. This ODR is available when the accelerometer is in low-power mode.

9. Accelerometer self-test limits are full-scale independent.

10. The sign of the linear acceleration self-test output change is defined by the STx_XL bits in a dedicated register for all axes.

11. The linear acceleration self-test output change is defined with the device in stationary condition as the absolute value of: OUTPUT[LSb]

(self-test enabled) - OUTPUT[LSb] (self-test disabled). 1LSb = 0.061 mg at ±2 g full scale.
