Is it possible to parallel multiple ADXL354 to reduce noise?

Question

In someone else's design circuit I've seen him using two or more ADXL35X's as seismometers ( Figure 1. I think he's using an analog MEMS because his output pins are only 16 pins.). The answers I've looked up on the web seem to be close to moving average filters. There are other similar circuits (Figure 2-3.) 
 My question is that for example digital ADXL355-MEMS can do moving average filtering to MCU through synchronous sampling. So can ADXL354 analogous MEMS directly use parallel connection to achieve noise reduction? Or do I need some external amplifier circuitry?

Of course you can. Like by using 16 ADXL354 parallel, the noise can be reduced from 20 to 5 &mu;g.

 Analog output is better because it is easy to sample them at the same time and by using external ADC, the performance would be better. 
 Last thing, I wonder where did you find these materials. Can you upload them or provide a website? I am also interested in it!

Parallel can reduce related noise, which can be seen from the former link I provided. This is a principle that has been proved in mangy other areas. 
 Because the output has 32k&Omega;, so their impedance is high. By connecting them together, you can just do the average instead of the simultaneous sampling or ADC reading.

How was your parallel project! 
 I wish you could see the expected noise reduction.
