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.
5. Set/reset pulse is automatically applied at each conversion cycle.
6.
“Self-test output change” is defined as: OUTPUT[mg]
(CTRL2 AST bit =1)
- OUTPUT[mg]
( CTRL2 AST bit =0 )
