Knowles 楼氏电子 SPK0415HM4H-B MEMS麦克风

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. Design variables include ever-smaller sizes, lower profiles and mounting options, increased output capacities, and new digital audio options that eliminate analog noise. 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.
