SPM0423HM4H-WB
Digital SiSonic^TM Microphone
The SPM0423HM4H-WB 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 SPM0423HM4H-WB 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:
 RF Shielded
 PDM Output
 Supports Dual Multiplexed Channels
 Ultra-Stable Performance
 Standard SMD Reflow
 Omnidirectional
