The CMM-4030DT-26354-TR is a digital MEMS microphone designed for compact audio capture with PDM (Pulse Density Modulation) output. It features omnidirectional sensitivity of -26 dB FS (typical) at 94 dB SPL and 1 kHz, with a frequency response range of 100 Hz to 10 kHz. The microphone operates at a supply voltage of 1.6 V to 3.6 V with typical current consumption of 0.54 mA, and achieves a signal-to-noise ratio of 65 dBA and acoustic overload point of 120 dB SPL. Its compact dimensions of 4.00 × 3.00 × 1.00 mm and reflow-solder-compatible surface-mount package make it ideal for portable consumer electronics, hearing aids, smart speakers, and IoT devices requiring space-constrained audio input.
