BMA400 sampling frequency accuracy

[flo56]

Hello,

I would like to know what is the expected accuracy for the sampling frequency.

My application requires to integrate acceleration data for a given duration to calculate the velocity change.

Then the sampling frequency accuracy error directly impacts the result.

(I didn't find this characteristic in the datasheet.)

Regard,

Florent

Hi flo56,

Could we know what is BMA400 ODR you used?

I plan to use to 400Hz ODR.

But I guess the same frequency error exists whatever the ODR selected, since they may be derived from the same main oscillator.
