Hello,

I have a question about the sampling rate of ADXL344.

There is a description about the accuracy of internal RC oscillator of ADXL345 as follows.

/51039#51039

Is the clock generation of ADXL344 accuracy of ±10%?

Is the ±10% the maximum value?

And, is the ±10% a expectation value or is it measurements value?

Moreover, does the accuracy worse by deteriorate over time?

Best Regards,

Mr.K

Hi Mr. K,

You can refer to figure 29 of ADXL362 datasheet, page12. ADXL344 internal clock accuracy deviation is similar with it. So, +/-20% could be a good assumption for min/max value. Of course, the typical deviation is +/-4%.
