CMM-2718AB-3815NC-TR Alternate View


2.75 x 1.85 mm, Analog, Bottom Port, Surface Mount, 1.8 Vdc, -38 ±1 dB, MEMS Microphone

Ideal for noise canceling applications, the CMM-2718AB-3815NC-TR is an analog MEMS microphone featuring omnidirectional directivity and a bottom port location. Thanks to its flat frequency response from 20 to 10,000 Hz, high signal-to-noise ratio (SNR) of 62 dBA, and high acoustic overload point (AOP) of 123 dB SPL, this MEMS microphone is well suited for use in active noise canceling microphone arrays.
