    New MEMS Microphones Carry Wide Operating Frequency Ranges

    CUI Devices’ Audio Group announced the addition of three new MEMS microphone models boasting wide frequency ranges from 20 to 20,000 Hz. The CMM-2718AB-38162W-TR, CMM-2718AB-38164W-TR, and CMM-2718AT-38164W-TR are all analog MEMS microphones featuring -38 dB sensitivity ratings and tight sensitivity tolerances of ±1 dB. Offering top or bottom port versions, these wide frequency range MEMS microphones are housed in compact, surface mount packages measuring as small as 2.75 x 1.85 x 0.90 mm, making them ideal for a variety of portable electronic devices and wearables.

    The models carry acoustic overload points (AOP) of 123 or 128 dB SPL, signal-to-noise ratios of 62 or 64 dBA, and current consumption as low as 150 µA. All models are omnidirectional and reflow solder compatible.

    The CMM-2718AB-38162W-TR, CMM-2718AB-38164W-TR, and CMM-2718AT-38164W-TR are available immediately with prices starting at $0.86 per unit at 500 pieces through distribution.
