Notes: 1. The product is factory calibrated at 3.3V. The device can be powered from 2.4V to 3.6V. Voff, So and Vt parameters will vary with
supply voltage.
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
5. Guaranteed by design
6. Contribution to the measuring output of the inclination/acceleration along any perpendicular axis
7. Self test “output voltage change” is defined as Vout(Vst=Logic1)-Vout(Vst=Logic0)
8. Self test “output voltage change” varies cubically with supply voltage
9. When full-scale is set to ±6g, self-test “output voltage change” is one third of the specified value
10.Minimum resonance frequency Fres=1.5KHz. Sensor bandwidth=1/(2*π*110KΩ*Cload) with Cload>1nF.
