SPH2878LR5H-1 SPH2878 AEC-Q103 QUALIFIED ANALOG BOTTOM PORT SISONIC™ MICROPHONE

PublishTime：2024-03-19

●The SPH2878LR5H-1 is a high-performance, bottom port analog silicon microphone, supporting both single-ended and differential modes. Using Knowles' proven high performance SiSonic™ MEMS technology, the SPH2878LR5H-1 consists of an acoustic sensor, a low noise input buffer, and an output amplifier. The microphone meets the AEC-Q100/103 quality standard, making it it ideal for automotive applications. The microphone has a flat frequency response with low LFRO and phase distortion enabling superior noise cancelling algorithm performance. Its high, 67 dB(A) SNR and 134 dB SPL AOP provides a large, distortion-free dynamic range for high-quality voice pickup. The microphone has an extended operating temperature range up to +105℃.
