1. The product is factory calibrated at 3.3 V. The operational power supply range is specified in
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 ratiometric to supply voltage
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. “Self-test output voltage change” varies cubically with supply voltage
9. Minimum resonance frequency Fres=2.0 kHz. Sensor bandwidth=1/(2*π*32kΩ*Cload), with Cload>2.5 nF
