Surface-mount MEMS microphones from Knowles that offer good sensitivity, high SNR, top or bottom port, analog or digital

About this Solution:

Knowles SiSonic™ surface mount MEMS

Built on CMOS/MEMS technology platform (originally launched in 2002), the SiSonic™ silicon-based microphone series is entering its fourth generation of development, with product shipments exceeding 5 billion units to date. The proven and evolving design series continues to support high-performance, high-density innovation in such applications as cell phones, 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.

Seltech is a global value-add supplier of these components and can provide technical support and competitive pricing:
