CMM-4030DT-26354-TR

Overview

The CMM-4030DT-26354-TR is a digital MEMS microphone manufactured by Same Sky. It features an omnidirectional acoustic port and outputs Pulse Density Modulation (PDM) signals. The device operates within a voltage range of 1.6 V to 3.6 V, with a typical supply current of 540 µA. It provides a sensitivity of -26 dB ±1 dB at 94 dB SPL and achieves a signal-to-noise ratio of 65 dB. The frequency response spans from 100 Hz to 10 kHz. The component is housed in a rectangular surface-mount package measuring 4.00 mm in length, 3.00 mm in width, and 1.10 mm in maximum height.

Feature Summary

Outputs digital PDM audio signals for direct interface with processors
Omnidirectional acoustic design ensures consistent sound capture from all directions
High signal-to-noise ratio supports clear audio recording in various environments

Applications

Voice recognition systems requiring digital audio input
Smart home devices utilizing voice command interfaces
Portable consumer electronics needing compact digital microphones

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing components. Confirm that the operating voltage requirements align with the target system's power rails. Ensure the PCB layout accommodates the specified dimensional constraints and top-port orientation for proper acoustic performance.

Selection Notes

Select this model for applications necessitating a digital output interface rather than analog. Consider the 1.6 V to 3.6 V supply range compatibility with low-voltage logic circuits. Evaluate the 4.00 mm x 3.00 mm footprint against available board space constraints during the mechanical design phase.

Part Context

This component belongs to the CMM series of digital MEMS microphones produced by Same Sky. It represents a silicon-based acoustic transducer designed for modern electronic devices. The product line emphasizes compact form factors suitable for dense circuit board layouts while maintaining high-fidelity audio capture capabilities.
