1. OP282GSZ Substitution Conclusion
The OP282GSZ is a conditionally viable substitute as it matches the original part in architecture (JFET), bandwidth, and supply voltage ceiling, but presents significant limitations. Key differences are: Its input bias current (3pA) and input offset voltage (200µV) are significantly superior to those of the TL082, offering distinct advantages in applications requiring high input impedance and DC precision, such as precision integrators or sensor front-ends. However, its lower slew rate (9V/µs), higher minimum operating voltage (9V), and lower output drive current (10mA) may result in insufficient performance or non-operation in single-supply low-voltage, high-speed signal, or heavy load-driving applications. Critically, it lacks the AEC-Q100 automotive-grade qualification of the TL082 and is therefore absolutely unsuitable for automotive or any field with stringent reliability requirements.
2. AD706JRZ-REEL Substitution Conclusion
The AD706JRZ-REEL differs drastically from the original part in core performance parameters, making it a largely non-viable direct replacement. The differences are: Its amplifier type is standard bipolar (Standard), not JFET, resulting in lower input impedance unsuitable for high-impedance signal sources. Its gain bandwidth product (800kHz) and slew rate (0.15V/µs) are far lower than those of the TL082 (4MHz, 16V/µs), severely degrading circuit bandwidth and signal processing speed. This disqualifies it for applications like audio or IF signal processing requiring moderate speed. While its input offset voltage (30µV) offers extremely high precision, it is only suitable for high-accuracy DC or low-frequency applications with no speed demands, representing a completely different application space.
