TDA200 and LM383 are obviously product or device names. Bruno Murari is obviously a person's name (a design engineer, as the sentence points out!), SGS is obviously a place where one works, likely a company.
You should have no issues with the term "reverse engineering" if you are on Hacker News. So that only leaves "automotive power amplifier using only five pins". You probably know what "automotive" and "five pins" means, though, so even less than that.
And then it's absolutely obvious that you won't know what a "power amplifier" is if you don't have some connection to electrical engineering, but it's useless to point that out. Imagine if every electrical engineer did that on articles on biology, chemistry or economic sciences.
These are names of things. The sentence structure makes that clear, and makes it clear how they relate. They are not "in-the-know" terms that are lacking definitions. It is not gibberish, just like the sentence "Jane gave Sue a letter from Bob" is not gibberish, even though nobody defined "Jane", "Sue", or "Bob".

Please don't be proud of ignorance.

Or to put it another way:
