SPM0687LR5H-1 WINFREY HIGH SNR, HIGH AOP ANALOG BOTTOM PORT SISONIC MICROPHONE The 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 PRODUCT FEATURES ended mode. This microphones high SNR enables far field voice pick up for IoT applications, and its high AOP provides a large dynamic Differential/Single-Ended Output range for barge-in applications. The microphones low phase Low Distortion /High AOP distortion lends to superior algorithm performance. Its differential High SNR mode configuration improves noise immunity to power supply Flat Frequency Response variations, allowing extension of microphone PCB traces.
