Hello, Noob question but I am trying to copy a schematic and I don't know too much about electronics. Are these the same circuit? The schematic says LM324 which I can find in the libraries but the one in easyeda has more connections and + and - are switched. ![image.png](//image.easyeda.com/pullimage/Z5XLH11ys5hV5lUJSUuDAwaCxSTzrWzKt43omXCl.png)![image.png](//image.easyeda.com/pullimage/uV8gCS673gNg2KTWrWbom8VcfaieLBhd4icrOZlg.png)

This EasyEDA Schematic Symbol is a military symbol so there is a symbol for each of the 4 devices in the package, with pin numbers to suit. * Please check against the manufacturer's datasheet.

So i guess to match with the schematic i should take this one? But should connection 4 and 11 always be connected with a power spply positive and negative? In my case a 9v battery? Thanks in advance! ![image.png](//image.easyeda.com/pullimage/vFPTV6I06YQqqdsYRxAT32OzF0fWVijifeCsYedL.png)

But what is the difference in the picture below between the 2 IC's? ![image.png](//image.easyeda.com/pullimage/gbH0WqFAnHMmSPufXan4ZdJXKnZ8LdtRP116AXj7.png)

You need to post the whole schematic so we can make sense of it before anyone can explain it.
