Table 3.
1. The product is factory calibrated at 3.3 V. The operational power supply range is from 2.4 V to 3.6 V. 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 ±8%.
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. When full-scale is set to ±6 g, “Self test output voltage change” is one third of the specified value at ±2 g.
10. Minimum resonance frequency Fres=1.8 kHz. Sensor bandwidth=1/(2*π*110kΩ*Cload), with Cload>1 nF.
