    PDF 509 KB an1681 2004年1月19日
    AI 生成的摘要: The document explains grounding techniques for PCB layouts using a dual op amp example on a single-layer copper board. It compares three grounding schemes: a center spine ground trace, an outer ground plane, and a split/star ground plane, highlighting the benefits of single-point grounding to minimize noise and antenna effects. It emphasizes following current paths, minimizing loop lengths, and ensuring close forward and return paths to reduce interference. The document also includes disclaimers on product use, quality grades, safety, and legal compliance.
