1. AD8602DRMZ-REEL Substitution Conclusion
Electrically compatible, but the performance differences require careful system-level evaluation. This part is footprint-compatible and operates over an overlapping supply range (2.7-5.5V). However, its quiescent current is significantly higher (750μA vs. 10.5μA). Bandwidth and slew rate are substantially improved (GBW 8.4MHz vs. 450kHz, SR 6V/µs vs. 0.08V/µs), while input offset voltage is degraded (1.3mV vs. 800µV). It is not suitable for ultra-low-power or high-precision DC applications but can be considered for circuits requiring higher speed, where increased power consumption is acceptable and input precision is less critical.
2. AD8532ARMZ-R2 Substitution Conclusion
Direct substitution is not generally recommended due to significant differences in input precision and power consumption. While the package is compatible, the supply range is slightly wider (2.7-6V), and output drive capability is stronger (250mA vs. 63mA), the input offset voltage is exceptionally high at 25mV (approximately 30x greater than the original). The quiescent current is also 750μA, and the amplifier is a "Standard" type, not CMOS. This part is unsuitable for circuits demanding high DC accuracy and its power consumption far exceeds the original design. It may only be applicable in applications insensitive to input error, requiring robust output drive, and where higher power dissipation is acceptable.
