Calli, Here's that microphone chip I was talking about. https://www.analog.com/en/products/ssm2167.html
I learned about it when I was looking to add an amplifier/compressor to my FT-817 and ran across this product. https://www.box73.de/product_info.php?products_id=945 and here's the magazine article on the chip. https://www.box73.de/file_dl/bausaetze/BX-817_3_w.pdf
