The sensitivity change over temperature for thermal accelerometers is based on
Guaranteed by measurement of initial offset and sensitivity.
Alignment error is specified as the angle between the true and indicated
Transverse sensitivity is the algebraic sum of the alignment and the inherent

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.
