Sensitivity starts to
degrade. Use S/R pulse to
restore sensitivity
Top Operating temperature range
1. Typical specifications are not guaranteed.
2. Verified by wafer level test and measurement of initial offset and sensitivity.
3. Typical Zero-g level offset value after MSL3 preconditioning.
4. Offset can be eliminated by enabling the built-in high-pass filter.
