What is overall range of G-force detection, resolution thereof, and mode of output?

Reviewer: from Ohio

I am a little out of practice with ICs in general, but it is my intention to use this to design G-force based shock notification units, measurement of up to 500 G is requisite. Is this technology able to accurately and consistently report a measurement of up to that magnitude?

All Electronics Response: No. I mean, we don't know for sure how many Gs you could measure with this (maybe another reader could answer definitely), but we don't believe it could do anything like what you're asking.
