Labs: LT1014 Op Amp equivalent to LM324
LTspice lacks an LM324 model, but the LT1014 is supposed to be a near equivalent (actually slightly better specs) with the same pinouts. The LT1014 is in the LTspice library.
The LT1014 data sheet is available at:

The advantage of the LT1014 is that it works as a comparator or an op-amp. Some op-amps have diodes on their inputs that will draw current if the device is used as a comparator, as explained here:
