Digital and analog MEMS microphones added to audio product group

CUI’s Audio Group has introduced a comprehensive line of MEMS microphones ideal for a variety of portable electronic devices. Boasting improved audio quality, performance and reliability, the CMM series is housed in exceptionally compact, low profile footprints measuring as small as 2.75mm x 1.85mm x 0.95mm. As reflow solder compatible components, these MEMS microphones will allow designers added flexibility where surface mount assembly is needed, making them ideal for audio recording and voice capture in smartphones, tablets, smart home devices, wearables, and more. The company’s MEMS microphones are omnidirectional and offered in analog or digital PDM output types with top or bottom port locations. Providing round or rectangular form factors, the series models carry sensitivity ratings from -44dB up to -26dB and signal to noise ratios from 5dBA up to 65dBA. These MEMS microphones also provide decreased vibration sensitivity, low current draw down to 80µA, and wide operating temperature ranges from -40C up to +105C. With tight sensitivity tolerances as low as ±1dB, the series is an excellent fit for array applications used to execute functions such as beam forming and noise cancellation. A unique inner chamber construction also gives more stable performance and provides these silicon-based microphones added protection against moisture and dust.
