The link below is a chart that contains a listing of silicon MEMS microphones and their accompanying performance parameters. Plus it contains the names and web site URLs of the companies that manufacture those devices. This chart first appeared as a support material for the article: Sound Check: Silicon MEMS Microphones Ready To Make Lots Of Noise, which appeared in the February 26, 2009 issue of Electronic Design magazine.
Here is the chart outlining the current offerings of today’s MEMS microphone manufacturers.
