1. TL082CMX/NOPB Substitution Conclusion
This variant is not a direct substitute for the original part due to mismatches in key electrical parameters. The primary discrepancy lies in its fixed supply voltage rating of 36V (both Min and Max), whereas the original part operates over a range of 10V to 30V. At the original design voltages (e.g., ±15V or single supply below 30V), the CMX variant may not function correctly or may exhibit different characteristics. Furthermore, its supply current (3.6mA per channel) is significantly higher than the original's 1.4mA, leading to a notable increase in system power dissipation. While it offers slightly higher output current and bandwidth, its input bias current and offset voltage are also larger, making it unsuitable for high-precision applications. Consideration is only viable if the design supply voltage is fixed at 36V and higher power consumption is acceptable; otherwise, it is not a valid substitute.
2. TL082BCD Substitution Conclusion
This variant is an excellent direct replacement or upgrade option, exhibiting high consistency with the original part's key parameters. Core specifications such as supply voltage range (10V to 30V), quiescent current (1.4mA per channel), gain-bandwidth product (3MHz), and slew rate (13V/µs) are identical, ensuring consistent basic operation and dynamic performance within the existing circuit. The main improvement is a reduction in the typical input offset voltage from 3mV to 2mV. In applications demanding higher DC precision, such as sensor amplification or integrator circuits, the BCD variant can offer better initial accuracy and lower output error. It represents a performance-enhanced version within the same series, features fully compatible packaging, and can be used as a drop-in replacement.
