New MEMS Microphone | CMM Series

Two new models of PDM output digital MEMS microphones have been introduced, optimized for microphone arrays and signal processing, supporting a low frequency range starting from 20Hz. Both models have a sensitivity of -26dB ±1 dB and an S/N ratio of 65 dB. The first model is the top-port type "CMM-4030DT-261075-TR" with dimensions of 4 x 3 x 1mm, and the second model is the bottom-port type "CMM-3526DB-26165-TR" with dimensions of 3.50 x 2.65 x 0.98mm. The MEMS microphones with digital signal output that support low frequency ranges are designed to be user-friendly for applications such as beamforming, noise cancellation, and sound source localization, where multiple outputs are synthesized. <CMM-4030DT-261075-TR> Dimensions: 4 x 3 x 1 mm Sensitivity: -26dB ± 1dB S/N: 65dB AOP: 120dB Frequency: 20Hz~10kHz <CMM-3526DB-26165-TR> Dimensions: 3.50 x 2.65 x 0.98 mm Sensitivity: -26dB ± 1dB S/N: 65dB AOP: 120dB Frequency: 20Hz~10kHz

A new model has been introduced featuring a MEMS microphone with a minimum size of 2.75 mm x 1.85 mm, which specifies a phase tolerance in the low frequency range of 20 Hz, making it ideal for microphone arrays and signal processing. This model is user-friendly for beamforming, noise cancellation, and sound source localization. It has an analog output type with a sensitivity tolerance of ±1 dB and a maximum S/N of 64 dB, covering the entire human audible range from 20 Hz to 20 kHz, making it suitable not only for multiple uses but also for a wide range of applications. With a thickness of 0.9 mm to 1.00 mm, it is a new product that can be easily integrated into wearable and portable devices. - Top Port Wideband MEMS Microphone Dimensions: 2.75 x 1.85 x 1.00 mm Sensitivity: -38 dB ± 1 dB S/N: 64 dB AOP: 128 dB Frequency: 20 Hz ~ 20 kHz - Bottom Port Wideband MEMS Microphone Dimensions: 2.75 x 1.85 x 0.90 mm Sensitivity: -38 dB ± 1 dB S/N: 62 dB ~ 64 dB AOP: 123 dB ~ 128 dB Frequency: 20 Hz ~ 20 kHz

The first IPX7 waterproof MEMS microphone has arrived. It features a digital PDM output with a size of 4mm x 3mm x 1mm and a top sound hole, enabling high environmental resistance in a very thin space. Additionally, it has a signal-to-noise ratio (S/N) of 65dB, and includes sleep mode and low power mode, allowing for energy-efficient operation in various applications such as voice recognition. For ECM, a model with φ4 x 1.5mm and IP65 rating has been added, equipped with a harness. It comes standard with a JST connector, making it a user-friendly and compact product that eliminates the need for soldering or connector crimping for small patterns. - CMM-3424DT-26165-TR (MEMS Microphone) Dimensions: 4 x 3 x 1 mm Sensitivity: -40 dB ± 1 dB S/N: 65 dB AOP: 120 dB Frequency: 100 Hz ~ 10 kHz - CMC-4015-40L170 (ECM) Dimensions: φ4 x 1.5 mm Sensitivity: -40 dB ± 3 dB S/N: 60 dB Frequency: 100 Hz ~ 20 kHz Connection: 170mm lead wire + JST ACHR-02V

A new minimum model of the CUI noise-canceling (bidirectional) electret condenser microphone has been introduced, featuring a diameter of φ4mm and a thickness of 1.5mm. This ultra-compact microphone, which has the characteristic of being difficult to pick up noise from distant sources, is ideal for communication applications such as headsets. Sensitivity: -44dB ± 3dB S/N: 55dB AOP: 120dB SPL Connection: Solder pad Frequency response: 100Hz ~ 1kHz Operating temperature: -40℃ ~ +85℃ Output impedance: 2.2kΩ *Includes 10pF and 33pF chip capacitors.
