    You can see this application note if you already have not:

    Hi @liaifat85  Thanks for your reply,

    In the application note that you have provided consisting of resolution which is related to timestamp, my issue is related to output values.

    Output values are stable but they are varying with 0.06 resolution. 

    Example: According to pic i have shared i am receiving roll value as -9.33, pitch values as -0.66 if we see those values i kept the device in steady position but if we observe sometimes roll is jumping to -9.28 suddenly and in the same way pitch also jumping with a deviation of 0.06
