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

  • \$\begingroup\$ i have tried an below circuit . it is not giving a output which i am giving in input. ni.com/cms/images/devzone/tut/vmbtsfev2596491556320455318.jpg \$\endgroup\$ – Vinoth Ravichandran Nov 14 '18 at 9:31

    \$\begingroup\$ 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. \$\endgroup\$ – Transistor Nov 14 '18 at 9:54

    \$\begingroup\$ "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? \$\endgroup\$ – JRE Nov 14 '18 at 11:27

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.

    \$\begingroup\$ 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. \$\endgroup\$ – henros Nov 14 '18 at 10:20
  • \$\begingroup\$ Thanks Koray. i got the circuit for unity gain buffer using UA741 and it is working. Now my need is fulfilled. eleccircuit.com/wp-content/uploads/2007/06/… \$\endgroup\$ – Vinoth Ravichandran Nov 14 '18 at 13:59
