Do we risk folding of out of band high frequency vibration components down to the band of interest.
Appreciate any level of information you can share here.

Hi @GSvoe.1 ,
the anti-alias filter is an analog filter just after the preamplifier, that cannot be configured in bandwidth.Instead, the downstream filters can be set according to, and the cutoff rate in this case is directly related to the ODR, according to the following table of the datasheet p.55:
The MEMS bandwidth (only for accelerometer ODR ≥ 1.67 kHz) is about 1.5kHz, see CTRL1_XL reg configurations.

Hello @Eleon BORLINI and @GSvoe.1 ,
I am working on sensor ISM330DLC to capture vibration data to perform FFT. and able to run application on ST MCU.
If sensor ISM330DLC is exposed for heavy vibrations in the range above 3.3kHZ, for example 4kHz.
Is there a way that sensor provides any information or register update to indicate to the user that vibration is over limited?
Please assist to solve the issue.
Regards,
Seenu
