SPM0437HD4H-B
Digital SiSonic^TM Microphone
The SPM0437HD4H is a miniature, high-
performance, low power, top port silicon
digital microphone with a single bit PDM
output. Using Knowles’ proven high
performance SiSonic^TM MEMS 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.
Features:
 Low Current
 PDM Output
 Supports Dual Multiplexed Channels
 Ultra-Stable Performance
 Standard SMD Reflow
 Omnidirectional
