SPM1437HM4H-B

Digital SiSonic^TMMicrophone

The SPM1437HM4H is a miniature, high-

performance, low power, top port silicon

digital microphone with a single bit PDM

output. Using Knowles’ proven high

Features:

 High Sensitivity

 Low Current

 RF Shielded

performance SiSonic^TMMEMS technology,

the SPM1437HM4H 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

 PDM Output

 Supports Dual Multiplexed Channels

 Ultra-Stable Performance

 Standard SMD Reflow

 Omnidirectional

recorders, and other portable electronic

devices where excellent wideband audio

performance and RF immunity are required.
