CMM-2718AB-38164-TR

Overview

The CMM-2718AB-38164-TR is an analog MEMS microphone manufactured by Same Sky. It features a rectangular surface-mount package with dimensions of 2.75 mm in length, 1.85 mm in width, and a maximum height of 0.95 mm. The device operates on a supply voltage range of 1.6 V to 3.6 V with a typical rating of 2 V. It exhibits an omnidirectional acoustic response and utilizes bottom porting for sound access. Key electrical specifications include a sensitivity of -38 dB ±3 dB at 94 dB SPL, a signal-to-noise ratio of 65 dB, and a frequency range spanning from 100 Hz to 10 kHz.

Feature Summary

Omnidirectional acoustic design suitable for uniform sound capture
Low power consumption optimized for battery-operated devices
Compact rectangular footprint enabling dense PCB layouts

Applications

Portable consumer electronics audio input
Voice recognition systems
Smart home voice assistants

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact sensitivity and SNR tolerances. Ensure the ordering part number matches the required acoustic performance characteristics. Confirm RoHS compliance status through the latest datasheet before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, omnidirectional analog microphone is required for space-constrained designs. Consider the 1.6 V to 3.6 V operating range for compatibility with various logic levels. Evaluate the 65 dB SNR specification against ambient noise requirements for the target application environment.

Part Context

This component belongs to the CMM series of MEMS microphones from Same Sky. The series offers various sensitivity and package options tailored for different audio fidelity needs. The CMM-2718 variant specifically targets compact applications requiring reliable analog output signals within a small form factor.

Replacement Considerations

Check for CMM-2718AB-38308-TR or CMM-2718AT-42108-TR as potential alternatives within the same family. Verify pinout compatibility and acoustic port orientation differences before substitution.
