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 SiSonicTM MEMS technology, the SPM0687LRSH-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 pick up for loT 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 microphone PCB traces.
