ODR deviation of lsm6dsox

Hello,

lsm6dsox is configured to 1667Hz ODR.

And I measured 'data ready interrupt' interval of 9 sensors.

It was between 1629.69 and 1683.57Hz.

I wonder if there is acceptable deviation criteria?

Hi @Community member ,

Please consider that the actual ODR frequency is a typical value (typ on the datasheet), that can slightly vary from the nominal value.

In particular, in HP mode the variation among samples can be +-1% typ, while in NM can be about +-2% (data on 100 characterization samples).

If you want to synchronize on ODR, you have to measure it sample by sample with the DRDY method, as you already correctly did.
