Hello,
I'm trying to connect an OpAmp to boost the overall voltage signal in my project. I'm using a 741 OpAmp as it's the only one they had at RadioShack.
My OpAmp only outputs a grand total of 1.6V, regardless if I feed 3V, 5V or 8V of AA batteries into it. I tried playing with different ratios with the two different resistors, but it's the same with different ratios and even if I just scrap all of the resistors altogether.
What am I doing wrong?
Here's a schematic of my circuit:
**broken link removed**
I'm extremely new to all of this so I'm hoping you guys can help me! I'm going NUTS here trying to figure this out for several days now and I can't come up with anything I can understand on Google or on the boards! I've read that the Output can switch between a "High" output and a "Low" output depending on the value of the Non-Invert Input, but I can't seem to get it working. I've tried to put several resistors on the Non-Invert Input but it doesn't change a thing.
Thanks so much for ANY help!
