I have noisy ADXL001 - I am wondering if this is correct output


The part is noisy.

to calculate to noise:

take the noise density: 3,3 mg/sqrtHz - datasheet  (70g Version - see datasheet
(3,3mg/sqrtHz*sqrt(22000*1.3) = 558mg Noise

1.3= correction factor as the low pass filter is not ideal

with 16mV/g

558mg equal to 8,9 mV Noise
