What could be wrong? Datashet problem is that your signal voltages and meters are not connected to power supplies, but are completely floating. If I apply reverse voltage with the g,324 battery, I see minus reading from the voltmeter. If I apply 9V as input there is no output.
Post as a guest Name. And above is a photo from my setup. I tried with another another brand it worked. I use 12VDC as Vcc.
Can’t tell entirely from the picture but it looks wired up ok unless there are loose connections. TomCarpenter Is the schematics right?
If you datashet -9V from a single rail supply, you’ve probably fried it. The opamp was defect definitely. And the opamp gets very hot. 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: I’d also try a different amplifier there are 4 in the IC, so try one of the other 3. Email Required, but never shown. Trouble dataaheet a voltage follower Ask Question.
Thats the only photo remained. But I think I figured out the problem.

WhatRoughBeast 49k 2 28 I checked many times. Probably pins were loose I didnt notice in the datashfet way. Andy aka k 10 I use the following data sheet: ThePhoton I used another IC now on the breadboard.
You are a good learner! It makes sense what you say. So you are saying the opamp is broken?

All grounds all connected. Home Questions Tags Users Unanswered. I can roughly see that, but have you probed each pin with the multimeter to check it is at the expected voltage – bl324.
I dont think thats problem here. 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. Have you probed dataeheet voltages on each pin to make sure they are correct?
Two browns are GND and Vcc for the opamp. I’m having trouble when I’m trying to make a voltage-follower from GL opamp. Sign up using Facebook. Sign up using Email and Password. I think you are right since in my second try with another lm I inserted it in the middle and it worked. I double checked my wiring and it matched the circuit schematics and datasheet.

For many of us, we can understand your circuit much more quickly by looking at your schematic than by reading your words.
