SiSonic™ MEMS MICROPHONES
Built on our 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 800 million 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.
• New MaxRF models eliminate GSM/TDMA burst noise and provide wide-band RF noise suppression
• Utlra Mini footprint – less than 11.5mm2 (SPU Series) • Slim Ultra Mini footprint 0- less than 8.5mm2 (SPQ Series)
• Digital microphones eliminate analog noise
• Integrated designs with differential or switchable gain
• "Zero height" for thinnest ever designs
The microphones can also be integrated with our patented IntelliSonic™ software and special porting designs to provide a precisely customized sound.
• Silicon structure for high degree of manufacturing repeatability and stable (predictable) acoustic performance
• Patented "free-floating" diaphragm is immune to shifts in microphone sensitivity caused by variable mechanical tension in traditional electret condenser microphone diaphragms
• Low mass, low size diaphragm produces excellent vibration sensitivity performance
• Excellent RFI and EMI suppression
• Excellent operating and storage temperature ratings -40C to 100C
• Versatile configuration and sound porting options for future microphone enhancements
• 45% less board space than 6x2.2 ECMs
• 30% lower profile height than ECMs
• RoHS Compliant and Halogen Free
• Highly shock resistant • Ideally suited for high volume applications
