Brief Description
LM324 is a Quad op-amp IC integrated with four op-amps powered by a common power supply. The differential input voltage range can be equal to that of power supply voltage. The default input offset voltage is very low which is of magnitude 2mV. The operating temperature ranges from 0˚C to 70˚C at ambient whereas the maximum junction temperature can be upto 150˚C. Generally, op-amps can perform mathematical operations.
