We are under testing ADXL345 evaluation board.
When I look at the datasheet, Scale factor is 4 mg/LSB.
But our test result shows that the noise density is bigger than the spec when DUT is moving.
Can anyone suggest how to get over noise problem?
Please look at the below test result.
1) It shows low noise when there is no acceleration.
2) When it starts moving, Noise desity is getting bigger.
