Hi! Total noob here. I'd just like to know the correct way to draw multi opamps like the TL072 and TL074. I can only select TL081. So I'm a little unsure how to do it here, and to get a correct simulation. Thanks Jesper |

Hi Jesper, take a look at this: I've just started from the TL071, then changed the model name to TL074. Then I copy-and-pasted to get four of them. I also named them (If you'd like, you can click to open my schematic above and then copy+paste into your own.) |

Thank you! What if I want voltage rails? Tl074 only have two inputs for all four op-amps..? |

I'm just really unsure what to do here? There is a huge difference in the simulation of OUT1, if I add the VCC to the second opamp or not. |

Ahh I was doing the simulation all wrong. Now when I do a Time Domain DC Sweep and use the VCC and GND to set opamp limits - it's working just fine. yay! Have to read up on those simulation types ;) Thanks again |
