CMM-4030DT-261280-TR

Overview

The CMM-4030DT-261280-TR is a digital MEMS microphone manufactured by Same Sky. It features a PDM output and an omnidirectional acoustic port located at the top of the package. The device operates within a supply voltage range of 1.6 V to 3.6 V and draws a typical operating 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 dBA. 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

Digital PDM interface for direct connection to audio processors
Omnidirectional sound pickup capability via top-port design
Low power consumption suitable for battery-operated devices

Applications

Voice recognition systems
Smart home voice assistants
Mobile communication devices

Procurement Notes
