CMM-4030DB-26354-TR

Overview

The CMM-4030DB-26354-TR is a digital MEMS microphone manufactured by Same Sky, formerly CUI Devices. It features a PDM output interface and operates within a voltage range of 1.6 V to 3.6 V. The device has a rated voltage of 2 V and consumes 540 µA of supply current. Its frequency response spans from 100 Hz to 10 kHz with an omnidirectional polar pattern. Sensitivity is specified at -26 dB ±3 dB relative to 94 dB SPL at 1 kHz. The signal-to-noise ratio is 64 dBA. The component utilizes bottom porting and solder pad termination in a 4.00 mm x 3.00 mm x 1.20 mm rectangular SMD package.

Feature Summary

Digital PDM output interface for direct connection to audio processors
Omnidirectional acoustic design for uniform sound capture
Bottom-port configuration optimized for PCB mounting

Applications
