The MM30 is a MEMS microphone with several
parameters that Knowles can modify programmatically, or
trim, after manufacturing and before testing. This means
that individual and matched microphones can be quickly
customized for optimal performance in different
applications. This document outlines the parameters that
can be trimmed and how changes to these impact other
performance parameters.
