    Bandwidth and filter of BMA456

    Bandwidth and filter of BMA456

    Hi,

     

    I'm trying to use the BMA 456 for some simple vibration measurement.

    Would be interesting to know:

    1) Does the BMA 456 has an anti-aliasing filter? As i read the datasheet, there is only an averaging filter.

    2) Where does the 3dB Cutoff frequency come from? is this a filter function of the sensor, or is this due to mechanical damping?

     

    Thank you very much for your help.

     

    Best Regards,

    Daniel

    Hello DMP,

    What is the vibration amplitude and frequency for your application?
