I have several questions about the self test feature of ADXL355 as follows. Could you please let me know ?
Q1. What is the purpose of the self test ?
Q2. Regarding datasheet, X-Axis is 0.3g, Y-Axis is also 0.3g and Z-Axis is 1.5g at Ta=25degC. When Ta will change higher or lower, will the output value also change ?
Q3. The customer tries to use the self test to adjust the output drift due to the temperature changing. Is it possible ?
Thank you for your post and your question. Sorry for the delayed response.
1. The purpose of self test is to make sure your device is functioning properly. Getting values that are typical of the self-test values will let you know that device is well within its working limits.
2. I'll talk with my team and will get back to you once I get a hold of information regarding this.
3. It would be better to base the adjustment from the datasheet.
Best Regards, John
Thank you very much for your support.
I wait for your answer about Q2.
The output value will also change but not significantly. May I know on what application you would like to use this for ?
Our customer wants to detect the tilt of the tower building due to an earthquake.
