Knowles' silicon microphone consists of an acoustic sensor, a low-noise input buffer, and a differential output amplifier

Image of Knowles Winfrey SPM0687LR5H-1 Silicon Digital MicrophoneThe Knowles SPM0687LR5H-1 is a high signal-to-noise ratio (SNR), high acoustic overload point (AOP), bottom port silicon microphone. Using Knowles' proven high-performance SiSonic™ MEMS technology, the SPM0687LR5H-1 consists of an acoustic sensor, a low-noise input buffer, and a differential output amplifier supporting optional single-ended mode. This microphone's high SNR enables far field voice pickup for IoT applications, and its high AOP provides a large dynamic range for barge-in applications. The microphone's low phase distortion lends to superior algorithm performance. Its differential mode configuration improves noise immunity to power supply variations, allowing extension of the microphone PCB traces.
