LIS2DW12: FIFO-Threshold-Interrupt Jitters at 1.6kHz

Hello ST-Community!When I'm using the LIS2DW12 at ODR=1.6kHz, the Interrupt for reaching the FIFO-Threshold is jittering with 1/ODR, but only if the threshold is greater than 12. If it's less or equal, everything is working fine.The buffer-Mode is se...

Potting an accelerometer (LIS2DS12)

I'm wondering if there are any concerns with acceleration measurement offsets and extra noise due to strain on the package from encapsulating it or potting it. I'm specifically looking at the LIS2DS12 if different packages have different answers to t...
