1. TL082ACDT Substitution Conclusion
The TL082ACDT can directly replace the original TL082CD, with improvements across several key performance parameters. Differences include: a wider supply voltage range (6–36V vs. 10–30V) for more flexible power supply scenarios; higher slew rate (16V/µs vs. 13V/µs) and gain bandwidth product (4MHz vs. 3MHz) for superior high‑speed signal processing; lower input bias current (20pA vs. 30pA), beneficial for high‑impedance sensing applications; and stronger output drive capability (40mA vs. 10mA), enabling direct driving of heavier loads. Additionally, the TL082ACDT is AEC‑Q100 qualified, making it suitable for automotive or high‑reliability industrial environments. Note, however, that if the original circuit relies on the specific slew rate or bandwidth limits of the TL082CD, high‑frequency stability should be verified after substitution.
2. TL082IDT Substitution Conclusion
The TL082IDT is also a viable drop‑in replacement for the TL082CD. Its technical specifications are identical to those of the TL082ACDT, offering the same performance enhancements (wide voltage, higher speed, stronger output, automotive qualification). The primary distinction lies only in the suffix “AC” versus “I,” which may indicate subtle differences in internal testing or specification grade—for instance, “AC” typically denotes tighter input offset voltage drift specifications. However, the provided parameter table does not detail these variations. Functionally, the TL082IDT can be substituted directly and is suitable for applications requiring automotive‑grade reliability. If the application has extremely stringent requirements for input offset voltage temperature drift, it is advisable to consult the detailed datasheet to confirm the specific advantages of the “AC” grade.
