so my lovely roommate showed me The Daily WTF, a blog dedicated to code that makes most good software engineers go, well, “wtf?” and its pretty funny.
In honor of that blog, I present a snippet from the op27/op37 datasheet:
(Which, of course I was referring to because I’m building a tape head preamplifier and its always better to just do what the datasheet says than think for oneself)
After a few hours of staring at the circuit and debugging and wondering “man why the hell is this railing?” I finally look back at the datasheet and realize: oh its in positive feedback, of course its railing.
Someone swapped the “+” and “-” pins in the example schematic.
Just goes to show, you can’t even trust the definative source of information.
