Problem with IIS2DH, sampling rate is not stable

LMont

Dear all, we have a problem with IIS2DH, in particulary the sampling rate is not the same chip by chip mounted on our PCB board. What is the issue? When we read with an oscilloscope the frequency on various board there is a shift of about 700Hz between many IIS2DH. For example we sample in Low Power Mode at 5376 Hz and when we read it with the oscilloscope we read 5556Hz in one PCB Board where is mounted the IIS2DH and in another board 4861Hz;

Could you please give me some answer, because it is very urgent for our project because next week will start the production.

Thanks

Lorenzo

How do you read the sampling rate? Do you use DRDY?

What is the sensor configuration?
