Description
By popular demand, I’ve made a run of the op-amp testers that I built and use in many of my videos. This tests many single, dual, and quad op-amps with standard pinouts. Each working op-amp on the chip flashes an LED. This tester is helpful in detecting dead chips, shorted chips, one or more outputs stuck high, or one or more outputs stuck low. Powered by 9V battery (not included).
Supports many common op amps:
Single Op Amps (any op-amp pin compatible to LM301/741/TL071/TL082)
Dual Op Amps (any op-amp pin compatible to LM1458/4558/TL072/TL082)
Quad Op Amps (any op-amp pin compatible to LM324/TL074/TL084)
