Table 3.
1. The product is factory calibrated at 3.0V. The operational power supply range is from 2.4V to 3.6V. Voff, So and Vt
2. Typical specifications are not guaranteed
3. Guaranteed by wafer level test and measurement of initial offset and sensitivity
4. Zero-g level and sensitivity are essentially ratiometric to supply voltage at the calibration level
5. Guaranteed by design
6. Contribution to the measuring output of an inclination/acceleration along any perpendicular axis
7. “Self test output voltage change” is defined as Vout
8. Minimum resonance frequency Fres=4.0kHz. Sensor bandwidth=1/(2*π*32kΩ*Cload)
