Wideband digital MEMS microphones optimal for microphone arrays and beamforming.
Two new models of PDM output digital MEMS microphones have been introduced, designed for microphone arrays and signal processing, with a low frequency range starting from 20 Hz. Both models have a sensitivity of -26dB ±1 dB and an S/N ratio of 65 dB, featuring the top port type "CMM-4030DT-261075-TR" measuring 4.00 x 3.00 x 1.00mm and the bottom port type "CMM-3526DB-26165-TR" measuring 3.50 x 2.65 x 0.98mm. The MEMS microphones with digital signal output that support low frequency bands are user-friendly products suitable for applications such as beamforming, noise cancellation, and sound source localization, where multiple outputs are synthesized.
