CMM-2718AT-42116-TR

Overview

The CMM-2718AT-42116-TR is an analog MEMS microphone manufactured by Same Sky. It features a rectangular surface-mount package measuring 2.75 mm in length, 1.85 mm in width, and 0.95 mm in height. The device operates within a voltage range of 1.6 V to 3.6 V with a supply current of 160 µA. It provides an omnidirectional frequency response from 100 Hz to 10 kHz. Key electrical specifications include a sensitivity of -42 dB ±3 dB at 94 dB SPL and a signal-to-noise ratio of 57 dBA.

Feature Summary

Omnidirectional acoustic porting for uniform sound capture from all directions
Low power consumption suitable for battery-operated portable electronics
Analog output interface compatible with standard audio processing circuits

Applications

Voice recognition systems requiring low-power always-on listening
Mobile communication devices such as smartphones and tablets
Wearable technology including smartwatches and fitness trackers

Procurement Notes

Verify the specific suffix code to ensure correct sensitivity tolerance and packaging configuration. Confirm RoHS compliance status for environmental regulations. Check moisture sensitivity level requirements for soldering processes. Validate lead time availability through authorized distributors. Ensure ESD protection measures are implemented during handling.

Selection Notes

Select this component when a compact form factor is required alongside moderate sensitivity. The 2.75 mm footprint allows integration into space-constrained designs. Compare SNR performance against higher-end models if noise immunity is critical. Consider the analog output requirement versus digital alternatives for system architecture compatibility.

Part Context

This part belongs to the Same Sky CMM series of MEMS microphones. The series offers various sizes and performance levels. The CMM-2718 variant specifically targets ultra-small applications. It shares the same core acoustic design principles as larger counterparts in the lineup.
