SiSonicTM MEMS Microphone

Built on our CMOS/MEMS technology platform (originally launched in 2002), the SiSonicTM 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.

Features

  • 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
