Four operational amplifiersOverview of LM324:
The LM324 includes four independent, high-gain operational amplifiers with internal frequency compensation. It is suitable for single电源 operation across a wide range of supply voltages and also functions in dual电源 modes. Under recommended operating conditions, the supply current is independent of the supply voltage. Its applications span sensor amplifiers, DC gain modules, and all other scenarios requiring operational amplifiers powered by a single supply.
