ADXL1001 Frequency Response

Hi,

We are using your model ADXL1001 and ADXL1002 chips in our packaged vibration sensors for various applications. We have been testing the frequency response of your sensors on our high frequency Spektra calibration s haker (certified from 10Hz to 50KHz) and we can not duplicate the test data results indicated in your datasheet. Typical frequency response results are a +/-1dB limit at 3kHz and the +/-3dB limit at ~7kHz. We are very experienced in accelerometer assembly and test and regularly test other sensors to 20kHz.

Is the data on the datasheet actual test results or simulated? Please offer suggestion for us to be able to duplicate your high frequency test results.

We can share our test setup and results if required.

Thank you
