CUI Devices


CUI Devices' Audio Group has introduced a comprehensive line of MEMS microphones which are ideal for a range of portable consumer electronics applications.

Offering high audio quality, performance and reliability, CUI Devices' CMM series is housed in compact, low-profile packages as small as 2.75mm x 1.85mm x 0.95mm, and in round and rectangular form factors. The microphones are compatible with reflow solder assembly processes, so they afford designers flexibility for use when surface-mount assembly is required.

Designers can choose from a wide range of operating parameters in order to meet the performance requirements of any design. Sensitivity ratings for the CMM series models vary in a range from -44dB up to -26dB. Tight sensitivity tolerance of as little as ±1dB means that the CMM series products work well in the microphone arrays used to perform functions such as beam forming and noise cancelation.

CUI Devices' MEMS microphones also deliver reduced vibration sensitivity, low current draw of as little as 80μA, and wide operating temperature ranges from -40°C to 105°C.

A unique inner chamber construction also provides more stable performance and gives these silicon-based microphones added protection against moisture and dust.
