The SPK01AOLR5H-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 SPK01A0LR5H-1 consists of an acoustic sensor, a low noise input buffer, and a single ended output amplifier. This microphone's high SNR enables enhanced consumer experience with Transparency Mode & Active Noise Cancellation on Ear Products. Its high SNR & AOP provide high dynamic range for a variety of loT products in a small form factor. The microphone's low phase distortion lends to superior algorithm performance.
