SPU0410LR5H-1
Zero-Height Precision SiSonicTM Microphone
The SPU0410LR5H-1 is a miniature, high-
performance, low power, bottom port
silicon microphone. Using Knowles’ proven
high performance SiSonicTM MEMS
technology, the SPU0410LR5H-1 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.
