I need to replace a surface mount ic in my amp and the markings are LM393 which the datasheet says it’s a dual differential comparator.
Now it seems like there are a ton of different ones LM393(https://www.kynix.com/components/LM393DR-General-purpose-Comparators-CAD-Models-Datasheet-Features.html), LM393DR, LM393D, LM393P, LM393N……etc the ic just says an LM393 Is there any difference?
