Optical MEMS microphones
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.
80 dBA SNR
Choose your digital interface
SBM100B is available in 3 digital output interfaces, PDM, I2S and TDM. PDM is a common stereo interface that supports very low latency and customizable bandwidth to suit the customer application. I2S is a multi-bit stereo output that simplifies the signal chain. 8 channel TDM is ideal for applications using microphone arrays where 8 microphone can be connected on a single data line.
Distortion proof in high-noise environments
Very loud environments can have high transient peaks that easily exceed the overload point of existing microphones. The SBM100B offers superior performance in very loud environments with an acoustic overload point up to 146dB SPL.
