GL324 Datasheet

I tried with another another brand it worked. Please edit your schematic to show what you actually connected.

Sign up using Facebook. I can roughly see that, but have you probed each pin with the multimeter to check it is at the expected voltage – e. Email Required, but never shown. What could be wrong?

Can’t tell entirely from the picture but it looks wired up ok unless there are loose connections. WhatRoughBeast 49k 2 28 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: ThePhoton I used another IC now on the breadboard.

Probably pins were loose I didnt notice in the first way. If I apply 9V as input there is no output. Andy aka k 10 I’m having trouble when I’m trying to make a voltage-follower from GL opamp. I double checked my wiring and it matched the circuit schematics and datasheet. So you are saying the opamp is broken?

And above is a photo from my setup. 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. I use the following data sheet: The opamp was defect definitely.

Your 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 9V battery, I see minus reading from the voltmeter. And the opamp gets very hot. Have you probed datasueet voltages on each pin to make sure they are correct? Trouble with a voltage follower Ask Question.

TomCarpenter Is the schematics right? It makes sense what you say.

I dont think thats problem here. You are a good learner!


But I think I figured out the problem. I’d also try a different amplifier there are 4 in the IC, so try one of the other 3. Home Questions Tags Users Unanswered.

I think you are right since in my second try with another lm I inserted it in the middle and it worked. Two browns are GND and Vcc for the opamp. If you applied -9V from a single rail supply, you’ve probably fried it. I use 12VDC as Vcc.
