    BMA400 low-pass filter

    BMA400 low-pass filter

    Hi,

    the BMA400 has the low-pass filter with bandwidth 0.24ODR or 0.48ODR. It is configurable by ACC_CONFIG0.filt1_bw.
    Is there anything else need to be configured to enable this filter? 


    In the BMA400 Desktop Development 2.0 User Manual on page 10 I see the checkbox "Filter Bandwidth" on figure 10, so is it possible to disable this filter? 

    Where can I found more information about this filter? 

    Regards,

    Hello Faustyna,

    You could see ACC_CONFIG0 register from data sheet, filt1_bw bit value 0 is for 0.4x ODR, filt1_bw bit value 1 is for 0.2x ODR. That you could enable or disable it by in "Filter Bandwidth" option..
