The LM741 is a widely used operational amplifier (op-amp) integrated circuit. It is one of the most popular and widely available op-amp chips, known for its versatility and general-purpose applications. The LM741 is a high-gain, direct-coupled amplifier with differential inputs and a single-ended output.



The LM741 op-amp is designed to amplify and manipulate analog signals. It is built using bipolar junction transistor (BJT) technology and operates with both positive and negative supply voltages. The chip is typically housed in an 8-pin dual in-line package (DIP).

CA741, CA741C, CA1458, CA1558, LM741, LM741C, LM1458 Data Sheet September 1998 File Number 531.4 0.9MHz Single and Dual, High Gain Operational Amplifiers for Military, Industrial and Commercial Applications The CA1458, CA1558 (dual types); CA741C, CA741 (single types); high-gain operational amplifiers for use in military, industrial, and commercial applications. These monolithic silicon integrated circuit devices provide output short circuit protection and latch-free operation. These types also feature wide common mode and differential mode signal ranges and have low offset voltage nulling capability when used with an appropriately valued potentiometer. A 10kΩ potentiometer is used for offset nulling types CA741C, CA741 (see Figure 1).
