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 sensitivity change over temperature for thermal accelerometers is based on

variations in heat transfer that are governed by the laws of physics and it is highly

consistent from device to device. Please refer to the section in this data sheet titled

“Compensation for the Change of Sensitivity over Temperature” for more

information.

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.
