The LS416 is a Video-Audio Interface IC manufactured by AIHuwen, constructed with a 48-pin Quad Flat No-lead (QFN) lead frame. It is RoHS compliant, meaning it does not contain restricted hazardous substances like lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs).The LS416 is a single-chip processor designed for processing audio and video signals. It integrates a USB 2.0 port, two digital data input/output lines, and four stereo audio output channels with independent volume control. It supports a variety of audio formats, including PCM, Dolby Digital, DTS, and MPEG-1 Layer 1/2/3.The LS416 also features high-speed digital filters and professional-grade components for optimizing signal quality, and a patent-pending audio technology that enhances signal-to-noise (SNR) ratio, allowing for a clearer audio output from digital input sources. It also has the ability to automatically detect audio signal frequency and correct for any audio source distortion.With its versatile processing capabilities and high signal quality, the LS416 is an ideal choice for transitioning audio and video signals between multiple devices.
