Sign up using Facebook. 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.
datasheeg I tried with another another brand it worked. So you are saying the opamp is broken? Your problem is that your signal voltages and meters are not connected to power supplies, but are completely floating.
I checked many times.

And the opamp gets very hot. Home Questions Tags Users Unanswered. WhatRoughBeast 49k 2 28 Thats the only photo remained.
I double checked my wiring and it matched the circuit schematics and datasheet. I use the following data sheet:.
I think you are right since in my second try with another lm I inserted it in the middle and it worked. I’m having trouble when I’m trying to make a voltage-follower from GL opamp. I use 12VDC as Vcc. Have you probed the voltages on each pin to make sure they are correct? Can’t tell entirely from the picture but it ratasheet wired up ok unless there are loose connections.
What could be wrong? It’s been more years than I can remember since using breadboard but shouldn’t the op-amp sit over the datasneet that runs horizontally through the middle: What you need to do is.

I can roughly see that, but have you probed each pin with the multimeter to check it is at the expected voltage – e. Sign up or log in Sign up using Google. If I apply reverse voltage with the 9V battery, I see minus reading from the voltmeter. For many of us, we can understand your circuit much more quickly by looking at your schematic datashdet by reading your words.
I’d also try a different amplifier there are 4 in the IC, so try one fl324 the other 3. Post as a guest Name. Trouble with a voltage follower Ask Question.

Email Required, but never shown. All grounds all connected. If you applied -9V from a single rail supply, you’ve probably fried it.
