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.
