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 External circuitry is required to extend the 3dB bandwidth (ref. Application Note: AN-
00MX-003)
5 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.
