MICROPHONES – MEMS
SiSonic
Built on our CMOS/MEMS technology platform, the SiSonic
MEMS microphone series is a step ahead of the competition with product
shipments exceeding 1 billion units to date. The proven and evolving design
series continues to support high-performance, high-density innovation
in such applications as cell phones, smart phones, laptop computers,
sensors, digital still cameras, portable music players, and other portable
electronic devices.
Design variables include ever-smaller sizes, lower profiles and mounting
options, increased output capacities, and new digital audio options that
eliminate analog noise. For manufacturers, surface mount designs eliminate
off-line subassembly production costs. Customized designs are supplied on
tape-and-reel and can be run through standard automatic pick-n-place
equipment during in-line surface mount manufacturing.
The microphones can also be integrated with our patented IntelliSonic
software and special porting designs to provide a precisely customized sound.
