RDI MEMS Microphones Enable Voice Services

Ultra-Compact, Top and Bottom Port MEMS Microphones

Mount Kisco, NY – July 30, 2019 - RDI today announced the addition of its new line of ultraminiature, high audio quality MEMS microphones to its extensive microphone components portfolio.

RDI’s MEMS microphones provide users with superb audio quality and performance in ultracompact, low profile packages measuring as small as 2.75 x 1.85 x 0.95 mm. Featuring omnidirectional directivity these microphones are reflow solder compatible, increasing their reliability and flexibility during the manufacturing process. RDI’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. Coupled with a very low current consumption, ease of design, and reduced vibration sensitivity, RDI’s MEMS microphones are ideal for a range of portable consumer electronics applications, including Voice Services, Artificial Intelligence, Smart Home Devices and much more.

Available in August 2019, the MEMS Microphone solutions enable a broad range of applications while maintaining high quality and low cost.
