MEMS microphones boost performance for ear & wearable solutions

KNOWLES SiSonic MEMS microphones: Titan (Digital), Falcon (Differential Analog), and Robin (Single Ended Analog) – provide advanced performance capabilities for space constrained ear and wearable applications.  Robin offers 66dB SNR and clean signals up to 130dB SPL with less than 1 percent distortion. The low distortion in loud environments enables high-fidelity sound capture and superior beamforming performance for the smallest of form factors. A similar level of signal clarity holds true for Falcon, and brings even higher signal-to-noise ratio (SNR) performance of 68.5dB further improving TWS applications like Ambient Awareness with less noise. In critical low frequency and speech band use cases, Falcon delivers 69dB. Likewise, Titan offers similar SNR performance to Falcon, while improving battery life by consuming 60percent lower current (470uA) than typical digital mics and lowering latency to 3us, making it ideal for Active Noise Cancellation (ANC) and always-on applications in digital architectures.
