ADIS16497-2BMLZ accelerometer data-Reg

Dear SIr/Madam,

We have ADIS16497-2BMLZ having 40g and 450 deg/s accelerometer and gyroscope. We have used for one of my project related to missile technology in this our launch acceleration sensed by sensor is 40g, But due to some vibration ADIS16497 is giving noisy data/erroneous data  during the flight time for some duration. what could be reason for that please let me know.

In ADIS16497 FIR filter is there so how to use that filter for getting filtered data directly from accelerometer instead of raw data. how to implement plz let me know.

Thanks

Ravi Kumar
