Overview of LM258DR by Texas Instruments
The LM258DR is a dual, 30-V, 700-kHz operational amplifier with operation temperature ranging from -25°C to 85°C and comes in an 8-SOIC package. Designed and manufactured by Texas Instruments, this operational amplifier (op-amp) stands out due to its precision, reliability, and efficiency across a wide temperature range. It is part of the broader category of Operational Amplifiers, a fundamental component in electrical engineering and electronics, involved in various signal processing tasks.
The LM258DR is built on a voltage-feedback architecture, providing a solid foundation for creating stable and high-performance circuits. Some of its most notable characteristics include a nominal common-mode rejection ratio (CMRR) of 80 dB, a maximum input offset voltage of 5000 µV, and a nominal slew rate of 0.3 V/µs. This op-amp is designed for a standard 5 V supply voltage but can operate up to a maximum of 32 V, and it consumes no more than 2 mA of supply current under nominal conditions, making it a versatile choice for both low and high-power applications.
Aside from its electrical characteristics, the LM258DR comes with several compliance certifications, including Pb-free and RoHS, meeting current environmental standards. The component is marked as “active” in its life cycle stage, indicating that it is still in production and widely available for procurement.
Industry Applications for LM258DR
The versatile design and electrical characteristics of the LM258DR make it suitable for a broad range of industry applications. While the following potential applications are conceptual and illustrative, requiring engineering analysis and verification, they highlight the part’s flexibility.
- Education and Research: The LM258DR might be used in educational lab equipment and research projects due to its easy-to-integrate SOIC package and broad operating temperature range. Its precise signal amplification capability supports experiments and prototypes involving analog signal manipulation.
- Consumer Electronics: In the realm of consumer electronics, the LM258DR could potentially be integrated into audio devices, such as amplifiers or mixers, due to its excellent common-mode rejection ratio and voltage gain. Its reliability across temperature variations also makes it suitable for outdoor electronic devices.
