Circuit not working? This IC tester can help you idenify if your op amp is the problem.

when it comes to an IC, it becomes very difficult to test the working of an integrated circuit. This project by lonesoulsurfer demonstrates the way of checking commonly used ICs like the LM358, LM386 and LM741 with his custom PCB.

As we all know, any operational amplifier IC has an inverting and non-inverting input, and this tester circuit uses the voltage comparator that is already present inside this IC. When there is a 50% duty cycle the output is always a square wave that results in flashing of the LED.
