Oh, #AliExpress sellers, never change... 😆
Ordered NE5532 opamps (10 MHz gain-bandwidth product, 9 volts/μs). Put them in my project, wasn't performing correctly. Set up the standard test circuit (gain of 10, non-inverting, output load 800 ohms + 100 pF) and started measuring them...
These things actually have a GBW of only ~520 kHz! And a maximum slew rate of less than 1.3 volts/μs! They're absolute junk!
I don't know what part they remarked to get these. When I first suspected they were fakes, I thought maybe the ancient and cheap NJM4558 (aka 4558D) - but even that should have a 1 MHz bandwidth. Maybe 4558s that failed quality control? 🤣 Anyone have an idea what they might be?
