CMM-2718AB-38316-TR

Overview

The CMM-2718AB-38316-TR is an omnidirectional MEMS silicon microphone manufactured by Same Sky. It features analog output and operates on a 2 VDC supply with a current consumption of 160 µA. The device has a sensitivity of -38 dB ±3 dB at 94 dB SPL and delivers a signal-to-noise ratio of 61 dBA. Its frequency range spans from 100 Hz to 10 kHz, with an impedance of 300 Ohms. The component utilizes bottom porting and measures 2.75 mm x 1.85 mm x 1.85 mm.

Feature Summary

Omnidirectional acoustic design for uniform sound capture
Analog output interface for direct signal processing
Low power consumption suitable for battery-operated devices
Surface-mount technology (SMT) compatible construction

Applications

Consumer electronics audio input systems
Portable communication devices
Voice recognition modules
Smart home audio sensors

Procurement Notes

Verify the specific suffix configuration against official documentation to ensure correct sensitivity and porting specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly.

Selection Notes

Select this component when a low-profile, omnidirectional analog microphone is required for compact designs. The 2 VDC operating voltage and 160 µA current draw make it suitable for energy-efficient applications. Verify that the 61 dBA SNR meets the specific noise floor requirements of the target audio application.

Part Context

This part belongs to the Same Sky CMM series of MEMS microphones. The series offers various sensitivity levels and porting options in a miniature rectangular package. The CMM-2718AB variant specifically denotes the -38 dB sensitivity and bottom-port configuration within this product line.
