1) It has internal LF filter, which is switched simultaneously with Sample Frequency (1600Hz LF - 3200 Hz sample; 800Hz - 1600Hz, ...)
Which type of digital LF filter has ADXL345 - Bessel, Butterworth, Chebyshev?
What about order of filter (filter's poles number - 2, 4?)
2) Does ADXL345 provide simultaneous sampling on X,Y and Z axes?
If there are delays between the samples for 3 axes, how much is it?
3) What about error of sample frequency and it's stability in temperature and time?
