CMM-3729AB-38108-TR

Overview

The CMM-3729AB-38108-TR is an analog MEMS microphone manufactured by Same Sky. It features a bottom port configuration and operates within a voltage range of 1.6 V to 3.6 V. The device provides a sensitivity of -38 dB and achieves a signal-to-noise ratio of 65 dBA. Its frequency response spans from 100 Hz to 10 kHz, with a maximum operating temperature of +105 °C.

Feature Summary

Omnidirectional acoustic design for uniform sound capture
Analog output interface for direct integration
Bottom port structure for specific mounting requirements

Applications

Voice recognition systems
Consumer audio recording devices
Industrial noise monitoring equipment

Procurement Notes

Verify the specific suffix AB-38108-TR against official documentation to confirm sensitivity and SNR ratings. Ensure compatibility with the required operating voltage range of 1.6 V to 3.6 V. Confirm that the bottom port orientation aligns with the mechanical design constraints of the target application board.

Selection Notes

Select this component when a high signal-to-noise ratio of 65 dBA is required for clear audio capture. The bottom port design is suitable for applications where top-side clearance is limited. Verify that the analog output type matches the input requirements of the connected processing circuitry.
