NOTES
1 Guaranteed by measurement of initial offset and sensitivity.
2 Alignment error is specified as the angle between the true and indicated axis of
sensitivity.
3 Transverse sensitivity is the algebraic sum of the alignment and the inherent
sensitivity errors.
4 The device operates over a 3.0V to 5.25V supply range. Please note that sensitivity
and zero g bias level will be slightly different at 3.0V operation. For devices to be
operated at 3.0V in production, they can be trimmed at the factory specifically for
this lower supply voltage operation, in which case the sensitivity and zero g bias
level specifications on this page will be met. Please contact the factory for specially
trimmed devices for low supply voltage operation.
