As reflow-soldering compatible components, these MEMS microphones will give designers added flexibility where surface mounting is required, making them suitable for audio recording and voice capture on smartphones, tablets, smart home devices, wearables, and more.

MEMS microphones are omnidirectional and available in analog or digital pulse density modulation (PDM) output types with top or bottom port locations. Offering round or rectangular form factors, the CMM series models have sensitivity ratings from -44 to -26 dB and signal-to-noise ratios from 57 to 65 dBA. These MEMS microphones also offer reduced vibration sensitivity, low current consumption as low as 80 microamps (µA), and wide operating temperature ranges from -40 to +105°C. With sensitivity tolerances as tight as ±1 dB, the CMM series is a perfect range for array applications used for functions such as beamforming and noise cancellation. The unique internal chamber construction also provides more stable performance and gives these silicone-based microphones added protection against moisture and dust.
