SPK0415HM4H-B Digital High-SNR SiSonicTM Microphone The SPK0415HM4H-B is a miniature, highperformance, low power, top port silicon digital microphone with a single bit PDM output. Using Knowles’ proven high performance SiSonicTM MEMS technology, the SPK0415HM4H-B 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 audio performance and RF immunity are required. The high Signal-to-Noise-Ratio (SNR) of the SPK0415HM4H-B enhances the performance of far-field applications and many complex, multi-microphone algorithms.
