CMM-2718AT-42108-TR

Overview

The Same Sky CMM-2718AT-42108-TR is an omnidirectional MEMS microphone featuring analog output and top port configuration. It operates on a 2 Vdc supply with a current consumption of 80 uA. The device provides a sensitivity of -42 dB with a 1 dB tolerance and achieves a signal-to-noise ratio of 60 dBA. Its frequency range spans from 100 Hz to 10 kHz, supported by a 300 Ohm impedance. The component measures 2.75 mm in length, 1.85 mm in width, and 0.95 mm in depth, designed for surface mount technology applications.

Feature Summary

Omnidirectional acoustic design suitable for uniform sound capture
Low power consumption optimized for battery-operated devices
High signal-to-noise ratio for clear audio reproduction
Compact rectangular footprint for dense circuit board layouts

Applications

Portable consumer electronics requiring low power audio input
Voice recognition systems utilizing analog signal processing
Handheld communication devices needing compact microphone solutions

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing. Confirm the analog output type matches your amplifier interface requirements. Ensure the top port orientation aligns with your enclosure acoustic venting design. Check RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Choose this model for applications prioritizing ultra-low current draw alongside high fidelity audio capture. The 2V operating voltage suits single-cell battery systems. Consider the 60 dBA SNR for environments requiring moderate noise rejection. The small form factor allows integration into space-constrained portable hardware designs.
