SPM0437HD4H-B

Digital SiSonic^TMMicrophone

The SPM0437HD4H is a miniature, high-

performance, low power, top port silicon

digital microphone with a single bit PDM

output. Using Knowles’ proven high

Features:

 Low Current

 PDM Output

 Supports Dual Multiplexed Channels

 Ultra-Stable Performance

 Standard SMD Reflow

 Omnidirectional

performance SiSonic^TMMEMS technology,

the SPM0437HD4H 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.
