Knowles SP Series SiSonic™ MEMS Silicon Microphones

Knowles SP Series SiSonic™ MEMS Silicon Microphones are high-performance, low power, top port silicon, digital miniature microphones. These digital microphones use SiSonic™ MEMS technology and consist of an acoustic sensor, a low noise input buffer, and either a sigma-delta modulator or output amplifier. Suitable applications include cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where wideband audio performance and RF immunity are needed.

The SPH06x and SPH16x MEMS Silicon Microphones are the world's first digital microphones to support the ultrasonic bandwidth.

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
 
Applications
  • Tier 1 mobile phones
  • Notebooks
  • Headsets
  • Digital still cameras
