MEMS Microphones
Built on our CMOS/MEMS technology platform, the SiSonic
™
silicon-based
MEMS microphone series is a step ahead of the competition with product
shipments exceeding 3 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.
MaxRF models eliminate GSM/TDMA burst noise and provide wide-band RF noise suppression
