The SPH0644LM4H-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 SPH0644LM4H-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
SPH0644LM4H-1 offers multiple performance modes.
