741 IC

The 741 IC is a classic general-purpose operational amplifier (op-amp) used for analog signal amplification. It is designed for voltage amplification, signal conditioning, and mathematical operations such as addition, subtraction, integration, and differentiation. The 741 IC is widely used in educational projects, DIY electronics, and basic analog circuits due to its simplicity and reliability.
