1. TL082CMX/NOPB Substitution Conclusion
Not feasible. The TL082CMX/NOPB is significantly inferior to the original TLE2082ACDG4 in key performance parameters. Its substantially lower gain-bandwidth product (4 MHz vs. 10 MHz) and slew rate (13V/µs vs. 40V/µs) render it severely inadequate for high-speed signal processing. Furthermore, its input offset voltage (5 mV vs. 700 µV) is an order of magnitude higher, which would cause severe degradation in DC accuracy. Additionally, its minimum supply voltage requirement is ±18V (a 36V total differential), making it incompatible with potential single-supply or lower-voltage (down to 4.5V) configurations used with the original part. The TL082CMX/NOPB is only suitable for applications with minimal speed and precision demands and cannot serve as a performance-equivalent substitute.
2. TL072CDT Substitution Conclusion
Conditionally feasible, but requires careful system requirement evaluation. The TL072CDT offers comparable input bias current (20 pA) and output current (40 mA) to the original part and features AEC-Q100 automotive-grade certification for high reliability. However, its gain-bandwidth product (4 MHz vs. 10 MHz) and slew rate (16V/µs vs. 40V/µs) are still only about 40% of the original's, leading to noticeably degraded performance in high-frequency or fast transient signal applications. Its input offset voltage (3 mV) also remains approximately 4 times higher than the original's (700 µV), potentially impacting output error in high-precision DC amplification circuits. If the application involves audio, mid-to-low frequency signal processing, or has specific cost/reliability requirements where some loss in speed and accuracy is acceptable, the TL072CDT can be considered as an alternative. Otherwise, it is not recommended.
