The datasheet for the device does not state the order of the LPF filters in the stop band. Should I assume it's 20dB/Decade attenuation?
Thanks.
Anthony.

Attempting to answer my own question, presumably the applied low-pass filter is just a programmable m-point smoothing filter (so its motion frequency response is going to be terrible - sin(Mw)/Msin(w)). At least the samples will look smooth!

Hi Antony, I unfortunately cannot share you the frequency response of the LPF in LIS2DTW12 (but are you referring to the one on the inertial data path or or the temperature path?) However please consider that if you want to optimize the data accuracy, you can work in HP mode applying the anti-aliasing filter (@400Hz). Regards
