Hi, I am stuggeling with the following problem. I have a divice that sends a bipolar singel ended signal (+/- 10V). I want to get this signal into another device, that accepts only differentioal inputs (+10V...-10V). There is no information about a common voltage mode. As far as I know I need to build with Op Amps a little circuit, that transforms this single ended signal into a differential signal. But here, I dont have any clue how to do this, because I dont know how to selsect the correct op amp and the resistors and other stuff around this circuit. I also want to test this on a breadboard, so I cant use smd /smt parts. Do you have any suggestions for this?
(I am beginner in electronics)
1. Please, read this article.
2. Also, look into the following circuit taken from here.
I want to get this signal into another device, that accepts only differentioal inputs (+10V...-10V).
Connect the -10V input to signal ground and feed your single ended signal output into the +10V input.
Grumpy_Mike:
Connect the -10V input to signal ground and feed your single ended signal output into the +10V input.
Does this work if both devices are connected to a common ground?
What I told you to do ensures they have a common ground.
Hi,
Do you have a manual for the device with differential input.
Can you please post a link to it?
Thanks.. Tom.. 
Since I do not know your voltage requirements I am guessing you are talking audio signals. The conversion can be accomplished with a small transformer. Try this link: https://www.shure.com/en-US/support/find-an-answer/transformers-when-to-use-and-how-does-it-work Here is a transformer source; https://www.lundahltransformers.com/microphone/
Here is another OpAmp circuit.
This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
