ADXL001 Output filtering

Thread Summary

The user inquired about the output filter and its effect on the ADXL001-70Z sensor's response, noting discrepancies in the data sheet and table recommendations. The final response directed the user to contact the Analog Devices support team for further assistance, as EngineerZone does not currently support this product. The user expressed frustration about the lack of consistent support and requested information on noise and frequency response changes with different capacitor values.

Data sheet recommends a 1nF capacitor on the output.

Table says a minimum of 1000pF (1nF).

Other devices publish the output resistance to make understanding the device behavior easier.

Data sheet of the ADXL001-70Z module says put your own filter on the output. Or put a shorting resistor on for R1 and use a 22nF cap for C2.

Is there more information on output filter and the effect of the response of the sensor?

  • Hi TFlynn-

    I’m sorry, EngineerZone doesn't currently provide a support community for Analog Devices' accelerometers.  We are planning to continue to add communities that cover other Analog Devices products over time, but for now, to get support on this product from ADI I would suggest submitting your question to the Analog Devices support team in your region.  You can find the appropriate support contact on our website at: http://www.analog.com/support
