Using 40 low frequency Mics.

I am working on a device that takes input from 40 microphones and send data to PC via Arduino.
I want to use low frequency microphones (5Hz onwards) with around 200-250Hz sampling for each mic.

For this purpose, my preliminary design is like this…
40 Mics → 40 PreAmp circuits → Mux Shield II → Arduino DUE → PC

Please suggest me suitable commercial available preAmp circuits and any suggestion on the design is most welcome.


Provide a link to the data sheet for the microphone.

It is ICS40300…

Have you looked at the manufacturer's application note for choosing a preamp?

Ya I’ve read that… I am finding some commercial available preAmp so that I avoid building 40 preAmps myself.
