4737 Analog Silicon Microphone

With its miniature 4.75 × 3.76 × 1.25mm form factor, the 4737 Analog Silicon Microphone offers excellent acoustic performance, including a high signal-to-noise ratio of 60dB and sensitivity of -26±3dB. Its omnidirectional pickup pattern and 100–10,000Hz frequency response make it ideal for smart wearables, voice interfaces, and other space-constrained devices. A low 100Ω output impedance ensures easy integration into a variety of analog audio systems with minimal signal loss.

 

• Exceptional Sensitivity: -26±3dB for precise and comprehensive sound reproduction.
• Ensuring a realistic and balanced audio experience, the omni-directional directivity captures sound from all directions.
• Wide Frequency Range: The extensive frequency range of 100–10000 Hz makes it versatile for a range of audio applications.
• Compact Design: The small dimensions of 4.75 x 3.76 x 1.25 mm make it easy to integrate into compact devices.

 

TWS (True Wireless Stereo Earbuds) The 4737 Analog Silicon Microphone is an ideal choice for TWS earbuds, offering a compact footprint and high SNR (60dB) for crisp voice capture and clear calls. Its omnidirectional pickup ensures consistent voice detection regardless of earbud orientation, while the low output impedance supports seamless analog signal integration with low-power audio chipsets. Reliable performance and miniaturized design make it well-suited for high-density, battery-powered devices.

Camera / Video Device For cameras and video-enabled devices, the 4737 Analog Silicon Microphone delivers clear, consistent audio to match high-resolution visuals. With a broad 100–10,000Hz frequency response and -26±3dB sensitivity, it accurately captures voice and ambient sound in compact enclosures. The omnidirectional pattern ensures balanced sound pickup from various angles, making it perfect for webcams, body cams, smart surveillance, and portable streaming gear.
