The LM741 is a typical single-channel operational amplifier, which does not require frequency correction, with short-circuit protection. The chip’s excellent performance characteristics ensure its wide use both in amateur radio practice and in analog electronics.
The LM741 provides 20 dB of signal gain and does not require frequency correction. It has short circuit protection.

You can see LM741 pinout bellow:
The micro-assembly has two external Offset pins for balancing, allowing you to adjust the offset of the operational amplifier input to zero. A potentiometer is best suited for this purpose. The IC’s supply voltage can range from +-18 to +-22 volts, depending on the modification, but the recommended interval is +-5 to +-15 volts.

The normal operating mode of an operational amplifier is the feedback mode. In this case, negative feedback is used, which reduces the overall gain but gives excellent stability.
