How precise is the Dualaxis AD22302 accelerometer?

Hello everyone


I am a mechanical engineering student currently working on a project,

wich involves working with an AD22302 Dual-Axis accelerometer.

It is capable of measuring +/- 70g on the x-axis wich is the one I am currently using.


My question is:

what is the accuracy of the device? I am able to find the non-linearity in the datasheet (attached to the post)

but that is about it and I need the overall accuracy. Any kind of help will be highly appreciated

  • If we were being very conservative, I would say that the difference in the peak shock, with respect to the no-shock output, should be better than 10% accurate, assuming that the majority of the energy is coming from the axis in question.  The cross-axis behaviors present another, independent error source that can reach 5% as well.  Since you are measuring 2x off of your present expectation, I would suspect that there are other errors in this process, which are not related to the sensor's behaviors.
