ADXL346 aliasing problem

Question

Hi, 
 according to the previous discussion. 
 "The ADXL346 has a single pole low pass filter with a -3dB bandwidth of 1.6kHz, so aliasing is possible above 1.6kHz in the roll-off region." 
 Is there any measure to solve this issue in this kind of digital output sensor? Or the only way is using analog output sensor? 
 
 thanks.

Hi RCheng823 , 
 Thank you for your post! You may refer to this article for added clarity: https://www.analog.com/en/technical-articles/elusive-tones-aliasing-effects-in-digital-mems-accelerometers-in-condition-monitoring.html 
 The solution will depend on your intended application. The article talks about ADXL355/354 but still could be applied to your decision on ADXL346. Hope this helps! Best regards, John)
