CUI Units’ Audio Group in the present day introduced the addition of two MEMS microphone fashions designed for energetic noise cancellation. The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR are analog MEMS microphones that includes omnidirectional directivity and backside or prime port areas, respectively. Due to their flat frequency response from 20 to 10,000 Hz, excessive signal-to-noise ratios (SNR) of 62 or 64 dBA, and excessive acoustic overload factors (AOP) of 123 or 128 dB SPL, these MEMS microphones are perfect for use in energetic noise canceling microphone arrays.
Housed in extraordinarily compact, low profile packages measuring as small as 2.75 x 1.85 x 0.90 mm, the fashions each supply sensitivity scores of -38 dB with tight sensitivity tolerances of ±1 dB. As reflow solder appropriate elements, these MEMS microphones afford designers extra flexibility the place floor mount meeting is required. The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR additionally carry present consumption as little as 150 microamps (µA) and working temperature ranges from -30 to 85°C.
The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR can be found instantly with costs beginning at $0.83 per unit at 500 items by distribution.
