CN0532 long term operating temperature

Hi, 

All CN0532 components are rated to 125C, but we did not characterize long term reliability of this circuit. Notice that the ADXL1002 (accelerometer on the CN0532) is on a over molded package, so package degradation/aging is expected at high temperatures. This would be translated as an offset drift at the output of the ADXL1002. Generally, we would expect the ADXL1002 to drift a few 100 mg over life time, but this is very difficult to quantify as is application dependent. 

I hope this helps, 

Pablo .

Hi Pablo,

On your reply above, did you mean 100 mVDC or mg?  I am trying to quantify what kind of drift to expect on the DC offset due to this package degradation/aging.

Thanks,
