Hello,In our application we've found quite big differences in ODR between different samples of the ISM330DHCX and also for different modes:For example if setting the ODR to 416 Hz we measure > 440 Hz. Furthermore when only ACC is active the ODR is 44...

This actually makes sense because the ODR is 26,667 kHz which means that between two samples are 37.5 us this would make three 12.5 us ticks. 25 us wouldn't make much sense.

Thank you, Eleon! @Eleon BORLINI

Hi @Eleon BORLINI ,thank you for your reply. We are already measuring the ODR to account for that in FFT calculations etc.However, is there any document showing how the internal clocks are working just to understand why there are differences between...

Hi Eleon,Thank you for your reply!I've read both datasheet and app note but I still think the value mentioned there is wrong. Here's how i come to this conclusion:Setup:IIS3DWB Eval Kit connected to 180 MHz Cortex M4 MCU via SPI (4 wires) @ 10 MHz, b...

What are the typical ODR deviations (Clock deviations) in the ISM330DHCX and other iNEMO Modules and is it somehow possible to connect external clocks?

Hello, I'm currently testing the IIS3DWB accelerometer. The Datasheet says that the Timestamp tick resolution ist 25 us. All my measurements show, that the real resolution is 12.5 us. Is this correct?
