CMM-2718AT-3817NC-TR
2.75 x 1.85 mm, Analog, Top Port, Surface Mount, 1.8 Vdc, -38 ±1 dB, MEMS Microphone
Ideal for noise canceling applications, the CMM-2718AT-3817NC-TR is an analog MEMS microphone featuring omnidirectional directivity and a top port location. Thanks to its flat frequency response from 20 to 10,000 Hz, high signal-to-noise ratio (SNR) of 64 dBA, and high acoustic overload point (AOP) of 128 dB SPL, this MEMS microphone is well suited for use in active noise canceling microphone arrays.
