The LM324 is a low-cost, quad operational amplifier (op-amp) integrated circuit (IC) that is widely used in electronic circuits. It was first introduced by Texas Instruments in 1972 and has since become a popular choice for a variety of applications.
The LM324 consists of four independent, high-gain, frequency-compensated operational amplifiers with a typical gain bandwidth product of 1 MHz. The device operates over a wide range of supply voltages, typically between 3V and 32V, and can be powered by a single supply or dual supplies.
The LM324 is known for its low input bias current and low offset voltage, which make it suitable for many precision applications. It also has a high open-loop gain and a large output voltage swing, which make it suitable for a wide range of signal conditioning and amplification applications.
The LM324 can be used in a variety of circuits, including active filters, voltage comparators, oscillators, voltage regulators, and many more. It is available in a variety of packages, including the standard 14-pin DIP (dual in-line package) and surface mount packages, making it easy to integrate into a wide range of electronic designs.
Overall, the LM324 is a versatile and widely used operational amplifier that provides a cost-effective solution for a variety of applications.
