CUI Devices is an electronic components manufacturer based just outside of Portland, Oregon, dedicated to innovations in an ever-expanding range of product technologies, including audio, interconnect, motion, relays, sensors, switches, and thermal management solutions. Housed in compact packages with profiles as low as 0.90 mm, CUI Devices’ electret condenser microphones and MEMS microphones offer a variety of performance options to meet the voice capture and audio recording needs of any design, available with omnidirectional, unidirectional, and noise canceling directivity.
The new CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR devices are analog MEMS microphones featuring omnidirectional directivity and bottom or top port locations, respectively. Thanks to their flat frequency response from 20 to 10,000Hz, high signal-to-noise ratios (SNR) of 62 or 64dBA, and high acoustic overload points (AOP) of 123 or 128dB SPL, these MEMS microphones are ideal for use in active noise canceling microphone arrays.
Housed in extremely compact, low profile packages measuring as small as 2.75 x 1.85 x 0.90mm, the models both offer sensitivity ratings of -38dB with tight sensitivity tolerances of ±1 dB. As reflow solder compatible components, these MEMS microphones afford designers additional flexibility where surface mount assembly is required. The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR also carry current consumption as low as 150 microamps (µA) and operating temperature ranges from -30 to 85°C.
The CMM-2718AB-3815NC-TR and CMM-2718AT-3817NC-TR are available immediately with prices starting at $0.83 per unit at 500 pieces through distribution. Please contact CUI Devices for OEM pricing.
