SPH1878LR5H-C;SPH1878 AEC-Q103 QUALIFIED ANALOG BOTTOM PORT SISONIC™ MICROPHONE

PublishTime：2022-04-26

●The SPH1878LR5H-C is a high-performance, bottom port analog silicon microphone, supper ng both single-ended and differential modes. Using Knowles' proven high performance SiSonic™ MEMS technology, the SPH1878LR5H-C consists of an acoustic sensor, a low noise input buffer, and an output amplifier. The microphone meets the AEC Q100/103 quality standa'd. making it it ideal (or automotive applications.The microphone has a flat frequency response with low LFROand phase distortion enabling superior noise cancelling algorithm performance. Its high, 67dB(A) SNR and 134 dB SPL AOP provides a large, distortion-free dynamic range for high-quality voice pickupJhe SPH1878LR5HC also provides a tighter sensitivity distribution to improve beam forming applications.
