MEMS Microphones Carry Wide Operating Frequency Ranges



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.
