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

  • Hi Jesper,

    Thank you for your post. As you can see in the datasheet, there are a lot of different condition-dependent error sources. Applying them to a composite error estimate requires understanding of those conditions.  With more information on what you are trying to measure and accomplish, I will be glad to walk you through the process of estimating this accuracy.  Can you offer a more detailed explanation of what you are trying to accomplish, along with any specific details you have on the actual acceleration profile (magnitude, time, frequency, if available/relevant).

    Look forward to the discussion.
