IIS3DWB ODR at selected bandwidth of ODR/4 on LPF2

Hello Community,

I am unsure what the ODR will be for the IIS3DWB sensor when we select the bandwidth of ODR/4.

Kindly suggest the relationships if available, I did not find any mention in the datasheet except for Table 45.

Are there any setting to select the ODR for the sensor? Is ODR autoselected as some multiple of the Bandwidth? Or is ODR always 26kHz irrespective of the bandwidth?

Regards

Hi @Chubs ,

for the IIS3DWB the ODR is set to 26.667 kHz, it is the bandwidth that is selectable.
you can refer to the table you posted to select it =)

Hello @niccolò,

Thanks for the update. Is there any way to reduce the ODR maybe at least ODR/2? Let me know.

Hi @Chubs , 
on this specific device the ODR is set, so you can't change it, but you can manually discard sample to adjust the ODR or even read the output with a timer set at the ODR you want =)
