NEW: ultrasonic microphone by Knowles Electronics, LLC

Knowles’ digital multi-mode ultrasonic microphone significantly improves ultrasonic SNR with our proprietary ultrasonic boost technology, enabling easier integration for precision applications. Digital microphones reduce the number of traces and inputs required, improve SNR, have superior noise immunity, and provide more functionality with multiple performance modes to end applications.

Ultrasonic Boost for Ultrasonic Support

Multiple Performance Modes (Sleep, Low Power, Standard, Ultrasonic Modes)

High SNR

Flat Frequency Response

Sensitivity Matching

RF Shielded

Omnidirectional

While Knowles industry-leading MEMS microphone technology, in bottom port configuration, offers flat frequency response in the standard audio bandwidth, they are also capable to support even higher frequency bands. Sensor designs are possible across a wide spectrum of applications requiring highly miniaturized solutions for sensing and actuation/signaling.
