Knowles Knowles Digital Multimode MEMS Microphone

Knowles Digital Multimode MEMS Microphone SPH0641LM4H1is a digital bottom port microphone with high Signal-to-Noise Ratio, multiple modes, and the lowest power consumption in the market. Ideal for consumer electronics, this new microphone enables voice controlled applications and maximizes battery life. The new 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. It delivers up to 3x less power consumption than other digital microphones and is 20% smaller in size.

Knowles SP Series SiSonic™ MEMS Silicon Microphones are high-performance, low power, top port silicon, digital miniature microphones. These digital microphones use SiSonic MEMS technology and consist of an acoustic sensor, a low noise input buffer, and either a sigma-delta modulator or output amplifier. Design variables include ever-smaller sizes, lower profiles and mounting options, increased output capacities, and new digital audio options that eliminate analog noise. Suitable applications include cellphones, smart phones, laptop computers, sensors, digital still cameras, portable music recorders, and other portable electronic devices where wideband audio performance and RF immunity are needed.
