Knowles SP Series SiSonic™ MEMS Silicon Microphones
Knowles SP Series SiSonic™ MEMS Silicon Microphones are miniature, high-performance, low power, top port silicon digital microphone. Using Knowles' proven high performance SiSonic™ MEMS technology, these digital microphones consist of an acoustic sensor, a low noise input buffer, and either a sigma-delta modulator or output amplifier. These devices are suitable for applications such as cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where excellent wideband audio performance and RF immunity are required.
The SPH06x and SPH16x MEMS Silicon Microphones are the world's first digital microphones to support the ultrasonic bandwidth.
