SPH6655LM4H-1 SPH6655 AEC-Q103 QUALIFIED DIGITAL BOTTOM PORT SISONIC™ MICROPHONE

PublishTime：2024-03-19

●The SPH6655LM4H-1 is a high-performance, low power, bottom port silicon digital microphone with a single bit PDM output. Using Knowles' proven high performance SiSonic™ MEMS technology, the SPH6655LM4H-1 consists of an acoustic sensor, a low noise input buffer, and a sigma-delta modulator. This microphone is ideally suited for automotive applications and AEC-Q103 qualified. Its high, 68 dB(A), SNR and 121dB SPL AOP provides a large, distortion-free dynamic range for high-quality voice pickup. Additionally, it features a wide frequency band for proximity detection and has a wide operating temperature range for automotive applications
