What you need to do is simulate this circuit — Schematic created using CircuitLab As you showed it, the measurements and signals, having no connection to any reference point common to the op amp, are never going to make sense. Probably pins were loose I didnt notice in the first way.
WhatRoughBeast 49k dxtasheet 28 ThePhoton I used another IC now on the breadboard. I use 12VDC as Vcc. If you applied -9V from a single rail supply, you’ve probably fried it. What could be wrong? If I apply 9V as input there is no output.

I can roughly see that, but have you probed each pin with the multimeter to check it is at the expected voltage – e.

Two browns are GND and Vcc for the opamp. Your problem is that your signal voltages and meters are not connected to power supplies, but are completely floating. You are a good learner!
But I think I figured out the problem.
For many of us, we can understand your circuit much more quickly by looking at your schematic than by reading your words. Andy aka k 10 The opamp was defect definitely. I dont think thats problem here.
As you showed it, the measurements and signals, having no connection to any reference point common to the op amp, are never going to make sense. What you need to do is.
Can’t tell entirely from the picture but it ratasheet wired up ok unless there are loose connections. Home Questions Tags Users Unanswered. It makes sense what you say.
I checked many times. It’s been more years than I can remember since using breadboard but shouldn’t the op-amp sit over the trough that runs horizontally through the middle: Thats the only photo remained. I think you are right since in my second try with another lm I inserted it in the middle and it worked. Post as dattasheet guest Name. Have you probed the voltages on each pin to make sure they are correct? I double checked my wiring and it matched the circuit schematics and datasheet.
I’d also try a different amplifier there are 4 in the IC, so try one of the other 3. TomCarpenter Is the schematics right?
