PUI Audio Microphone, 160dB Maximum Sound Pressure Level, 20kHz Maximum Frequency Response - AMM-3738-B-R
This microphone is a Compact MEMS sensing device designed for audio capture in electronic and automation systems. It functions as an omnidirectional sound transducer suitable for integration where a small, low-impedance sensor is required, operating across a wide audible range and compatible with low-voltage circuits.
Features and Benefits:
• Omnidirectional pickup gives uniform sensitivity in all directions
• 300Ω impedance supports consistent electrical matching in systems
• -38dB sensitivity enables detection of low-level signals
• 160dB maximum SPL tolerates very loud acoustic events
• 1.5V to 3.6V operating range permits battery and low-voltage operation
• 300Ω impedance supports consistent electrical matching in systems
• -38dB sensitivity enables detection of low-level signals
• 160dB maximum SPL tolerates very loud acoustic events
• 1.5V to 3.6V operating range permits battery and low-voltage operation
Applications
• Suitable for environmental noise monitoring in factories
• Ideal for voice capture in embedded automation controls
• Used for acoustic diagnostics in mechanical systems
• Can be used for audio input in low-power sensing modules

What frequency range can be expected from this sensor?
It provides a wideband response from 0.02 kHz up to 20 kHz, covering subsonic frequencies to the upper limit of human hearing.
How is the device typically connected to a host circuit?
The element uses a pin-type connector for direct interfacing with PCB- or cable-mounted connectors.
What mechanical size considerations affect PCB layout?
The Active element measures 3.76mm in length, which should be allowed for on mounting footprints.
Is the microphone compatible with high-SPL measurement tasks?
Yes, its 160 dB maximum sound pressure capability permits use where transient or sustained high levels occur.
