741 Op-Amp subcircuit model for Labs 3 and 5
Note: There is no connection for the Rp resistor in this SPICE model (i.e., the
"offset null" connection). This resistor is used to balance out asymmetries
in real op-amps caused by transistor mismatch. Since simulations ignore the
random variations between devices that is introduced in manufacturing, there
is no need for this resistor in simulations. Just leave it out.

* To use a subcircuit, the name must begin with 'X'. For example:
* X1 1 2 3 4 5 uA741
*
* connections: non-inverting input
* | inverting input
* | | positive power supply
* | | | negative power supply
* | | | | output
