ADIS16305 Gyro stability following shock / drop test

Hi Mems Experts,

 

 

Our customer who is using the ADIS16305 dropped one of his boards on the floor.  Afterwards, he noted that there was a significant shift in the gyro offset.  Where the Gyro offset was previously -100, the Gyro is apparently now reading 0.2.

 

Is this type of offset normal after a significant shock?  The datasheet notes a survivability shock specification of 2000G but of course this doesn’t guarantee any specific maximum offset shift for a given shock rating.  Will it be difficult to restore the device to calibration?

 

Any info you can provide would be greatly appreciated.

 

Kind regards,

Quenton
