MEMS (Micro-Electro-Mechanical Systems) microphones are advanced miniature devices essential in mobile, ear, IoT, and automotive applications. As industry leaders, we offer microphones that feature ultra-compact sizes, low profiles, and various mounting options to suit diverse design requirements. Our microphones deliver high-quality audio with increased output capacities and digital solutions that minimize analog noise.

The SPH0655LM4H-1 is a miniature, high-performance, low power, bottom port silicon digital microphone with a single bit PDM output. Using Knowles' proven high performance SiSonicTM MEMS technology, the SPH0655LM4H-1 consists of an acoustic sensor, a low noise input buffer, and a sigma-delta modulator. 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. In addition, the SPH0655LM4H-1 offers multiple performance modes.
