LIS2DH12 bandwith and aliasing

Hello,

is there any kind of anti aliasing filter in the LIS2DH12 the datasheet is not clear to me.

In the datasheet of the LIS2HH12 there are some settings according to analog aliasing filters. So is this filter not present in the LIS2DH12 or only suitable for high data rates?

best regards

hi Hartmann, in LIS2DH12 the antialias filter is not selectable, and the max bandwidth is determined by the ODR/2, while in LIS2HH12 the filter is selectable according to the AN4662, p.10
