I want to duplicate signal generator output to dual. since i want to use same signal to two different place. Is this possible without amplifying and inverting the signals. Let me share some circuit.

i just tried using two OP-AMP 741 and failed.

I have only basic knowledge in electronics.

Finally found working using below circuit...

finally found working using this circuit

  • what have you specifically tried, and how did that fail? – Marcus Müller Nov 14 '18 at 09:24
  • look into a voltage follower –  Nov 14 '18 at 09:25
  • i have tried an below circuit . it is not giving a output which i am giving in input. http://www.ni.com/cms/images/devzone/tut/vmbtsfev2596491556320455318.jpg – Vinoth Ravichandran Nov 14 '18 at 09:31
  • Depending on what you are doing, it can be as simple as a splitter (putting the two sinks in parallel) or very complicated. A 741 might be adequate for audio, but is in general a bad choice. What kind of signal is it, and what are you doing with it? – JRE Nov 14 '18 at 09:33
  • That is a very simple circuit, and should work. – JRE Nov 14 '18 at 09:34
  • My signal might be a sine or square. i want to make dual output from single function generator. please suggest and share some circuit. – Vinoth Ravichandran Nov 14 '18 at 09:37

    Please post the schematic in the question and not as a link in a comment where most people won't see it or won't bother. – Transistor Nov 14 '18 at 09:54

    "Failed" can mean a lot of things. Did the 741 explode? No output? Low output? Distorted output? Too high output? Oscillated? The 741 ate your hamster? What failed? – JRE Nov 14 '18 at 11:27
  • The circuit you linked to is an inverting amplifier. – JRE Nov 14 '18 at 11:44
  • Thanks all for the help. unity gain buffer is satisfied my requirement. – Vinoth Ravichandran Nov 14 '18 at 14:01

You should use 2 unity gain buffer parallel for this. You may find details about unity gain buffer in google.

output of signal generator will be connected to the input of each unity gain buffer input. output of each buffer will be same.

    This should work, but only over a limited range of frequencies - particularly for 741s! Without more details of the expected usage, it is not possible to say more. – user131342 Nov 14 '18 at 10:20
  • Thanks Koray. i got the circuit for unity gain buffer using UA741 and it is working. Now my need is fulfilled. https://www.eleccircuit.com/wp-content/uploads/2007/06/unity-gain-follower-by-ic-lm741-1.jpg – Vinoth Ravichandran Nov 14 '18 at 13:59
