LM324 is a 14pin IC consisting of four independent operational amplifiers (op-amps) compensated in a single package. Op-amps are high gain electronic voltage amplifier with differential input and, usually, a single-ended output. The output voltage is many times higher than the voltage difference between input terminals of an op-amp.

These op-amps are operated by a single power supply LM324 and need for a dual supply is eliminated. They can be used as amplifiers, comparators, oscillators, rectifiers etc. The conventional op-amp applications can be more easily implemented with LM324.

THE OP-AMP AS A COMPARATOR

The OP-AMP can compare two signals (voltages). This is called a COMPARATOR or DIFFERENTIAL AMPLIFIER (amplifies the difference between two signals). There are two arrangements – connection to a single rail or dual rails. The animations below show the output for each configuration:
