LSM6DSO analog anti aliasing

Hi,

I would like to confirm if setting LSM6DSO ODR to 6.66KHz and LPF2 to ODR/10 (resulting to 666Hz bandwidth), then setting a FIFO decimation factor of 8 (resulting to 833hz FIFO ODR) will work in preventing aliasing for signals above 417Hz?

 

We have discovered with LSM6DSL that it doesn't work that well, but looking at a previous post where the LSM6DSO is recommended (Solved: LSM6DSL anti-aliasing filters do not appear to be ... - STMicroelectronics Community). So I would like to confirm it before we do a hardware change in production.

 

Thank you.
