L3GD20H non-linearity

Question asked by mcculloch.ian on Sep 27, 2016
I am using the L3GD20H in an application where I am measuring the angular velocity of a pendulum.  I want to calculate as accurately as possible the kinetic energy.  I have calibrated for gyro zero-offset drift, however non-linarity is causing slightly different reading when the pendulum is rotating clockwise and counter-clockwise.  This is within the range indicated by the datasheet.

My question is, how stable is the non-linearity of the gyro with respect to time, temperature etc?  Can I expect to be able to calibrate the non-linearity once for each L3GD20H device and not have to recalibrate in the future?
