the SE570/NE570 IC is like a dual op-amp in that the same circuit is duplicated twice within the IC package. How do I go about doing a three part custom schematic symbol for this critter ?!
(detailed steps pls!)
Kicad calls them 'unit’s. I haven’t needed to do it in a while so I can’t be of much more help. Going to the symbol editor and put ‘dual op’ in the search bar and that might help get you started.
First:
Have you a personal library in which to place this symbol?
What shape do you wish for your symbol… rectangular, triangular, etc?
Have you ever created a symbol before?
It does not really work that way.
First put in some effort yourself, and when you get stuck, show us where you got stuck and also that you’ve put in some effort.
