Table 3.
1. The product is factory calibrated at 3.3V. The operational power supply range is from 3.0V to 3.6V. Voff, So and Vt
2. Temperature range -40°C to +85°C. All the parameters are specified @ Vdd =3.3V, T = 25°C unless otherwise noted
3. Typical specifications are not guaranteed
4. Guaranteed by wafer level test and measurement of initial offset and sensitivity
5. Zero-g level and sensitivity are essentially ratiometric to supply voltage at the calibration level
6. Guaranteed by design
7. Contribution to the measuring output of an inclination/acceleration along any perpendicular axis
8. “Self test output voltage change” is defined as Vout
9. Minimum resonance frequency Fres=2.0kHz. Sensor bandwidth=1/(2*π*32kΩ*Cload)
