1. AD8602ARZ-REEL Substitution Conclusion
The AD8602ARZ-REEL outperforms the original part in key performance metrics. Its lower input bias current (0.2 pA vs. 1 pA) and significantly better input offset voltage (80 µV vs. 1.5 mV) provide clear advantages in applications requiring high precision and low DC error, such as sensor signal conditioning. It also offers higher slew rate (6 V/µs vs. 4.5 V/µs) and output current (50 mA vs. 35 mA). However, its minimum operating voltage is slightly higher (2.7 V vs. 2.5 V), and it lacks AEC-Q100 automotive qualification. Therefore, it is not suitable for automotive electronics or applications requiring high-reliability certification. In non-automotive general-purpose circuits, it can serve as a replacement, provided voltage headroom is verified.
2. AD8602DRZ-REEL Substitution Conclusion
The AD8602DRZ-REEL shares most parameters with the AD8602ARZ-REEL, including low input bias current, high slew rate, and high output current. However, its input offset voltage (1.3 mV) is similar to that of the original part (1.5 mV). This makes it a suitable direct replacement in AC or general amplification applications where DC accuracy is not critical. Similarly, it has a higher minimum operating voltage (2.7 V) and lacks automotive-grade certification. It is therefore applicable in industrial or consumer electronics. If the original design is intended for automotive environments or requires operation down to 2.5 V, substitution is not feasible.
