1. AD8602DRZ-REEL7 Substitution Conclusion The AD8602DRZ-REEL7 can substitute for the NCS20032DR2G, but this is considered a non‑ideal replacement. The suitability must be evaluated based on key differences in the specific application. There are three primary deviations: First, the input offset voltage increases from 500 µV to 1.3 mV, resulting in a significant reduction in DC accuracy. This makes it unsuitable for applications requiring high‑precision signal amplification. Second, the lower supply rail rises from 1.7 V to 2.7 V, preventing its use in any single‑supply or low‑voltage system operating below 2.7 V. Third, the quiescent current per channel increases from 275 µA to 750 µA, raising power dissipation by approximately 2.7×. This is unfavorable for battery‑powered or low‑power designs. However, the AD8602 offers advantages in lower input bias current (0.2 pA vs. 1 pA) and slightly higher bandwidth (8.4 MHz vs. 7 MHz). It may be preferable in specific scenarios where high input impedance and enhanced high‑frequency response are critical.
