MORELLO SPH0641LM4H-1 MEMS Microphone
Knowles introduces its SPH0641LM4H-1, a digital bottom port MEMS microphone
Knowles' SPH0641LM4H-1 is a digital bottom port MEMS microphone with high signal-to-noise ratio, multiple modes, and the lowest power consumption in the market. Ideal for consumer electronics, this microphone enables voice controlled applications and maximizes battery life.
The microphone utilizes Knowles' low power, "Always On, Always Listening" technology to provide a high SNR component with the lowest power draw in the world, lower than the conventional analog microphone and analog-to-digital converter combination. Compared to other solutions, this digital multi-mode microphone adds value to consumer electronics by delivering up to 3x less power consumption than other digital microphones and is 20% smaller in size.
This product supports a longer battery life and enables accurate voice recognition in various settings, such as social gatherings and sporting events.
