For many of us, we can understand your circuit much more quickly by looking at your schematic than by reading your words. If you applied -9V from a single rail supply, you’ve probably fried it. Probably pins were loose I didnt notice in the first way.
Please edit your schematic to show what you actually connected. Post as datassheet guest Name. Andy aka k 10 What could be wrong? Have you probed the voltages on each pin to make sure they are correct? I think you are right since in my second try with another lm I inserted it in the middle and it worked.
ThePhoton I used another IC now on the breadboard. Trouble with a voltage follower Ask Question. Thats the only photo remained. 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: And the opamp gets very hot.
I’m having trouble when I’m trying to make a voltage-follower dztasheet GL opamp. I double checked my wiring and it matched the circuit schematics and datasheet.
WhatRoughBeast 49k 2 28 If I apply 9V as input there is no output. Can’t tl324 entirely from the picture but it looks wired up ok unless there are loose connections. I checked many times. All grounds all connected. I dont think thats problem here. If I apply reverse voltage with the 9V battery, I see minus reading from the voltmeter.

So you are saying the opamp is broken? TomCarpenter Is the schematics right?
It makes sense what you say. I tried with another another brand it worked. What you need to do is simulate this circuit — Schematic created using CircuitLab As you showed it, gl342 measurements and signals, having no connection to any reference point common to the op amp, are never going to make sense.
I use the following data sheet:. Sign up using Email and Password. The opamp was defect definitely. I can roughly see that, but have you probed each pin with the multimeter to check it is at the expected voltage – e. What you need to do is. But I datasheef I figured out the problem.
