SPU0409HD5H-PB
SiSonicTM Microphone
The SPU0409HD5H-PB is a miniature, high-
performance, low power, top port silicon
microphone. Using Knowles’ proven high
performance SiSonicTM MEMS technology,
the SPU0409HD5H-PB consists of an
acoustic sensor, a low noise input buffer,
and an output amplifier. 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:
Small package
Ultra-Stable Performance
Standard SMD Reflow
Omnidirectional
