Top Operating temperature range -40 +85 °C
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.
