I checked many times.

Probably pins were loose I didnt notice dstasheet the first way. TomCarpenter Is the schematics right? It makes sense what you say. If I apply reverse voltage with the 9V battery, I see minus reading from the voltmeter.

Your problem is that your signal voltages and meters are not connected to power supplies, but are completely floating. The opamp was defect definitely.

I double checked my wiring and it matched the circuit schematics and datasheet. I use 12VDC darasheet Vcc.

What you need to do is simulate this circuit — Schematic created using CircuitLab As you datasbeet it, the measurements and signals, having no connection to any reference point common to the gl3244 amp, are never going to make sense. Have you probed the voltages on each pin to make sure they are correct? I use the following data sheet:.

Two browns are GND and Vcc for the dataaheet. I think you are right since in my second try with another lm I inserted it in the middle and it worked.

What could be wrong? If I apply 9V as input there is no output. I tried datqsheet another another brand it worked. I dont think thats problem here. Thats the only photo remained. Can’t tell entirely from the picture but it looks wired up ok unless there are loose connections. I use the following data sheet: As you showed datashee, the measurements and signals, having no connection to any reference point common to the op amp, are never going to make sense.

You are a good learner! Trouble with a voltage follower Ask Question. I’d also try a different amplifier there are 4 in the IC, so try one of the other 3. But I think I figured out the problem.

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: So you are saying the opamp is broken?

Andy aka k 10 ThePhoton I used another IC now on the breadboard. For many of us, we can understand your circuit much more quickly by looking at your schematic than by reading your words.
