PUI Audio Microphone MEMS

This microphone is a Compact MEMS transducer designed for integration into audio electronics and industrial systems, delivering consistent signal capture for control, monitoring and voice interfaces. It operates at low supply voltages and interfaces via a pinned connector, making it suitable for projects where space and power consumption are constrained.

• 300Ω impedance for predictable signal matching and attenuation control
• -29dB sensitivity enabling detection of low-level acoustic signals
• Pin-type connector simplifies mechanical mating and replacement
• Operates from 2V to 3.6V to suit low-voltage system designs
• Conforms to RoHS and REACH supporting regulatory material requirements

• Suitable for embedded voice input in automation controllers
• Ideal for audio sensing in industrial machinery monitoring
• Used with low-power sensor nodes in electrical systems
• Can be used for acoustic detection in mechanical diagnostics

It uses a pin-type connector which requires compatible mating pins on the host assembly for mechanical and electrical connection.

It functions across a 2V to 3.6V operating range, allowing it to run from low-voltage rails and supply-regulated domains without additional converters.

Design for a 300Ω source impedance when selecting input stages or matching networks to ensure expected frequency response and gain.

The microphone is a MEMS sub-type suited to Compact placement in electronic assemblies and can be integrated where small form-factor acoustic sensors are required.
