MEMS Microphones

Audio Microphones

Our MEMs microphones provide users with improved audio quality and performance in compact, low profile packages measuring as small as 2.75 x 1.85 x 0.95 mm. Featuring omnidirectional directivity with analog or digital pulse density modulation (PDM) output types, these microphones are reflow solder compatible, increasing their reliability and flexibility during the manufacturing process. CUI’s MEMS microphones offer top port or bottom port versions, while carrying sensitivity ratings from -44 up to -26 dB, signal to noise ratios from 57 up to 65 dBA, and sensitivity tolerances as low as ±1 dB. With a low current draw, simple design, and reduced vibration sensitivity, our MEMS microphones are ideal for a range of portable consumer electronics applications, including smart phones, tablets, smart home devices, and more.
