SSM2167 Microphone Compressor Breakout

The Analog SSM2167 is “mic conditioner.” I’m most interested in the adjustable compressor. A microphone compressor is a great way to get main gain out of HF radios.  The SSM2167 costs less than USD$2 in single unit quantities. It is available in surface mount only packages.

To test this part, I came up with a dip converter for breadboard use. All pins are broken out. If the smd parts are soldered on then the gain is fixed and the compressor is set to 1:4.
