Texas Instruments LM741CN Operational Amplifier, 1MHz, 8-Pin DIP

The Texas Instruments LM741CN is a classic, general-purpose operational amplifier that delivers robust and reliable performance for a wide array of analogue circuit designs. It offers a unity-gain bandwidth of 1MHz and a slew rate of 0.5V/µs, making it suitable for applications requiring moderate speed and precision. This device operates from a wide supply voltage range of ±10V to ±18V, providing excellent flexibility for various power supply configurations.

Engineered for reliability, the LM741CN incorporates several protective features that make its application nearly foolproof. It includes overload protection on both the input and output stages, preventing damage from signal overloads. Furthermore, the amplifier is designed to avoid latch-up when the common-mode input range is exceeded, ensuring stable operation even under non-ideal conditions. Its design freedom from oscillations simplifies circuit stabilisation.

This operational amplifier is presented in a durable, 8-pin plastic dual in-line package (PDIP), ideal for through-hole mounting on prototyping boards or in final product assemblies. It is a direct, plug-in replacement for older industry-standard amplifiers like the LM709, LM201, MC1439, and 748 in most applications, offering improved performance while maintaining pin compatibility.
