MEMS microphones carry wide operating frequency ranges

The CMM-2718AB-38162W-TR, CMM-2718AB-38164W-TR, and CMM-2718AT-38164W-TR are all analogue 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 0.90mm, making them ideal for a variety of portable electronic devices and wearables.

The models carry acoustic overload points (AOP) of 123 or 128dB SPL, signal-to-noise ratios of 62 or 64dBA, and current consumption as low as 150µA. 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. Contact CUI Devices for OEM pricing.
