741 Op Amp Internals

The internal circuitry for the UA741/LM741.

NOTE: THE SWITCH ABOVE THE POSITIVE VOLTAGE SOURCE MUST BE SET TO OPEN BEFORE SIMULATING. IT CAN BE CLOSED AFTER STARTING.

I don't know why, but for some reason EveryCircuit tends to goof up starting complex circuits. It works fine afterwards.

1Khz Sine: Non-Inverting Input (+)
2Khz Sine: Inverting Input (-)
Blue wire: Output

You can also see the headroom and slew rate in the simulation. Neat!
