Hi guys,

I've reverse-engineered the SSM2167 Microphone Board Preamplifier Low Noise COMP Compression DC 3V-5V Module and wanted to ask whether any improvements can be made? Due to space constraints, I'm only using SMD components.

This mod is for improving output from mic in Android Head Units. Schematics attached.

 

Hello,

Perhaps the manufactureres page might give you the wanted info:
