1.

The product is factory calibrated at 3.0 V. The operational power supply range is from 2.7 V to 3.3 V. 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 at the calibration level ±8%.

5.

Guaranteed by design.

6.

Contribution to the measuring output of an inclination/acceleration along any perpendicular axis.

7.

8.

Minimum resonance frequency Fres=2.0 KHz. Sensor bandwidth=1/(2*

π*32 kΩ*Cload), with Cload>2.5 nF.
