1. AD8682ARZ Substitution Conclusion The AD8682ARZ can be considered a performance‑upgrade substitute for the TL082BCD, though certain characteristic differences should be noted. Its primary advantages include lower input bias current (6 pA vs. 30 pA) and superior input offset voltage (350 µV vs. 2 mV), resulting in lower signal error in applications requiring high input impedance and high DC accuracy—such as sensor amplification and precision integrator circuits. Additionally, its quiescent current is significantly lower (210 µA per channel vs. 1.4 mA per channel), which benefits low‑power designs. However, note that its slew rate is lower (9 V/µs vs. 13 V/µs), which may lead to slightly inferior large‑signal, high‑frequency response compared to the TL082. The device is pin‑compatible and its supply range covers the TL082 requirement (9 V to 36 V), allowing direct replacement in most scenarios; nevertheless, applications sensitive to slew rate or requiring high‑speed performance should be carefully evaluated.
