CUI has added analog and digital MEMS microphones to its audio product group, boasting improved audio quality and very small footprints. The CMM series of omnidirectional microphones offers a choice of analog or digital pulse density modulation (PDM) output with top or bottom ports in packages as compact as 2.75×1.85×0.95 mm.

Their small size and compatibility with reflow solder processes make them suitable for audio recording and voice capture in smart phones, tablets, smart home devices, and wearables.

Both round and rectangular form factors are available, while inner chamber construction enables stable performance with added protection against moisture and dust.
