ICM-20602 Output Wrapping

By helium4amc , 5 November 2018

Hi, I am using the ICM-20602 and have seen a couple of issues where the output wraps under high rate/acceleration. Is this a known issue and is there a workaround?

With the rate wrapping, increasing the rate range from +/-500°/s to +/-2000°/s fixed the issue (at the expense of resolution) as our application never sees rates this high.

With the accelerometer wrapping (which we have just seen in a results file back from a customer), I am curious whether increasing the range (currently +/-2 g, increased to +/-16 g) will help, as the application is likely to see shocks in excess of the maximum range (I am more than happy for the output to just saturate!).

I have attached a screenshot showing the accelerometer wrapping. If required, I could probably dig out the same for the gyro, but the gyro issue was some months ago.
