Introducing the next generation audio sensor technology from SoniCrest, made possible by advanced MEMS expertise. Fabricated with state of the art micro-machining techniques and unique patented processes. The SMO01 and SMO02 series microphones are pushing the industry into the age of silicon technology, bringing new performance and innovation that allows new applications in consumer electronics, telecommunications, and industrial applications not previously encountered.

SoniCrest silicon microphones are integrated with specialized pre-amplification ASIC to provide high sensitivity, high signal to noise ratio output from a capacitive audio sensor. Packaged for surface mounting and high temperature re-flow assembly, it routinely operates in adverse conditions that would permanently damage conventional microphones.
