Dear sir or madame,
we build up some three axis accelerometer based on your ADXL1004 and ADXL1005 mems sensors. In the intended application we now realized that there are high amplitudes at very high frequencies which activate the OR feature of the sensor. Unfortunatelly your implementation of the OR feature destroys the sensor signal instead of just informing with the dedicated OR-pin on the IC and simply clipping the signal at two times the nominal acceleration range.
So I have two questions to make the accelerometers usable in this application:
- Is there a possibility to disable the OR feature? Or at least disable the destruction of the sensor signal in case of OR?
- Do you have any experience in defined decoupling of the body vibrations with any kind of foam, rubber, ... which we can apply between the dut and our accelerometer? Frequencies above 10kHz and accelerations higher than 100g (and 500g) are not relevant for our analysis and could be damped away.
Many thanks and best regards,
Fabian
