1. TS972IDT Substitution Conclusion
The TS972IDT can serve as a replacement for the ALD2732ASAL, but key differences must be considered: its input bias current (200 nA) is four orders of magnitude higher than that of the original part (10 pA), making it unsuitable for low‑noise applications sensitive to input current, such as high‑impedance sensor signal conditioning. Additionally, its offset voltage (1 mV) is about 1.7 times that of the original (600 µV), resulting in slightly reduced accuracy. Advantages include significantly higher gain‑bandwidth product (12 MHz vs. 1.5 MHz) and slew rate (4 V/µs vs. 1.9 V/µs), making it better suited for applications requiring greater bandwidth. It also supports a wider supply range (2.7–10 V) and is AEC‑Q100 qualified, which enhances its suitability for automotive or industrial environments.
2. AD8032ARZ‑REEL7 Substitution Conclusion
The AD8032ARZ‑REEL7 can be used as a high‑performance alternative, but compatibility must be evaluated: its input bias current (450 nA) is considerably higher than that of the original device (10 pA), likewise rendering it inappropriate for micro‑current amplification applications. Its offset voltage (1 mV) is also higher, reducing precision relative to the original part. The main advantages are substantially greater bandwidth (80 MHz) and slew rate (35 V/µs), making it well‑suited for high‑speed signal processing, along with a wider supply range (2.7–12 V). However, note that its output current capability (15 mA/ch) may be limiting; if the original design drives low‑impedance loads, load‑driving capability should be verified.
