PUI Audio Microphone, 20kHz Maximum Frequency Response, -26dB Sensitivity - DMM-4026-B-I2S-R


This omnidirectional MEMS microphone is designed for low-voltage digital audio capture in industrial and electronic systems. It converts acoustic signals into an I2S output suitable for integration with digital processors and control units, offering broad frequency coverage for voice and environmental sensing in automation and machine‑interface contexts.

Features and Benefits:


• Omnidirectional pickup for uniform sound capture across angles
• Frequency response of 0.02 to 20 kHz for wideband audio detection
• Sensitivity -26 dB enabling detection of low‑level signals
• Operates from 1.5V to 3.6V for low‑voltage system compatibility
• Pin‑type connector for straightforward board‑level connection
• REACH and RoHS conformity supporting regulatory material limits

Applications


• Suitable for voice detection in machinery safety systems
• Ideal for acoustic monitoring in environmental control units
• Used with embedded controllers for hands‑free interfaces
• Can be used for sound‑based diagnostics in electromechanical equipment

What electrical supply range is required for reliable operation?


It accepts a supply between 1.5V and 3.6 V, allowing use with common low‑voltage logic rails and battery‑powered electronics.

How does the microphone perform across the audible spectrum?


The device responds from 0.02 kHz up to 20 kHz, covering subsonic monitoring through the full audible range for voice and machine‑noise analysis.

What connector type should I expect for PCB integration?


It employs a pin‑type connector, compatible with soldering or pin‑header mounting on PCB layouts.

Is the device suitable for applications demanding material‑restriction compliance?


The microphone meets REACH and RoHS requirements, indicating it conforms to the specified substance restrictions.
