The SPH0641LM4H-1 is a miniature, high-performance, low power,
bottom port silicon digital microphone with a single bit PDM output.
Using Knowles’ proven high performance SiSonic™ MEMS technology,
the SPH0641LM4H-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
SPH0641LM4H-1 offers multiple performance modes.
