SPM0423HM4H-WB
Digital SiSonicTM 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 SiSonicTM 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
