CMR-2747PB-A

Overview

The CMR-2747PB-A is a 6.0 mm electret condenser microphone manufactured by Same Sky (formerly CUI Devices). It features an analog output with noise-canceling capabilities, providing a sensitivity of -47dB ±3dB at 94dB SPL. The device operates within a frequency range of 100 Hz to 20 kHz and requires a supply voltage between 2 V and 10 V. It utilizes PC pins for PCB mounting and is designed for applications requiring reliable audio capture in environments where background noise reduction is necessary.

Feature Summary

Integrated noise-canceling technology for improved signal clarity
Electret condenser design for consistent analog audio output
PC pin termination for secure printed circuit board mounting

Applications

Consumer electronics audio input systems
Industrial communication devices
Automotive infotainment microphones

Procurement Notes

Verify the manufacturer designation as Same Sky, formerly CUI Devices, to ensure component authenticity. Confirm that the specific variant matches the noise-canceling specification and the 6.0 mm form factor required for your enclosure. Ensure the operating voltage range of 2 V to 10 V aligns with your system power supply before integration.

Selection Notes

Select this component when a compact 6.0 mm footprint is required alongside active noise cancellation. It is suitable for designs needing a wide supply voltage tolerance up to 10 V. Compare sensitivity specifications against other models if higher gain is needed, but note that this unit provides a standard -47dB response optimized for general-purpose voice pickup.

Part Context

This microphone belongs to the electret condenser category from Same Sky. It serves as a direct replacement for legacy CUI Devices components in existing designs. The product line focuses on providing reliable audio sensing solutions with standardized dimensions for easy integration into various electronic assemblies without significant redesign.
