The next generation MEMS microphones

True studio-quality, high dynamic range and easy product integration. All in a small package.

The SBM100 product series

The SBM100 series offers a MEMS microphone with true studio-quality performance. The patented optical ultra-low noise MEMS microphone features 80 dBA Signal-to-Noise-Ratio (SNR), 146 dB SPL Acoustic Overload Point (AOP), <0.5% Total Harmonic Distortion (THD) and yet with low power consumption in a small MEMS package with digital output – a quantum leap in performance compared to today’s mainstream MEMS microphones. sensiBel sets a new performance benchmark and brings a true studio-quality performance MEMS microphone in a small package to your products.

The SBM100 series is the first-generation optical MEMS microphone from sensiBel with the following key parameters.

Crystal clear recordings

Crystal clear audio and sound capture require low microphone self-noise (high SNR) and low harmonic distortion. The sensiBel team believe you should expect the same audio recording quality in your portable device as with a professional studio microphone. For more sophisticated audio applications, small form-factor microphone array products can be enabled by sensiBel’s extremely low self-noise.

Distortion proof in high-noise environments

Distortion proof in high-noise environments

Undistorted crystal clear audio and sound capture in a high-noise environments requires a high dynamic range. Distortion-free recordings are now possible in high-noise environments like at a rock concert. Loud thumps and other low frequency sounds that would typically distort your audio, are easily handled by the sensiBel microphone. sensiBel provides 146 dB SPL AOP @ 1kHz and can handle up to 150 dB SPL at lower frequencies.

Flexible platform solutions. A digital interface makes system integration easy and provides robustness to noise pick-up.

Flexible platform solution

A digital interface makes system integration easy and provides robustness to noise pick-up. PDM interface enables low-latency and easy integration with current systems. I2S interface can be utilized for unlimited transfer of the entire dynamic range. TDM interface makes multi-microphone integration easy. sensiBel offers all these options.
