Real vs Fake NE5532 OpAmp ICs – Fake Version is “Bare minimum to operate as opamp”
It’s almost comical what counterfeiters try to pass as legitimate pieces of hardware. Zeptobars has full-size images of this real (left, obviously) and fake (right, double-obviously) NE5532 opamp – the left image is a genuine TI-brand IC and the right image is sold as “Ti” at approximately 1/20th the cost of the real deal component:
We have spotted yet another real/fake pair of very common microchip. This time it is Ti NE5532. NE5532 is a very fine opamp which will do just fine in 99% of audio applications. I afraid it got at bit of bad fame due to fakes which have quantitatively slower slew rate and sound objectively worse.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
