1. LMV721M5X/NOPB Substitution Conclusion
Given compatibility in supply voltage range (2.2V to 5.5V) and package (SOT-23-5), the LMV721M5X/NOPB can serve as a functional replacement for the TSV911ILT. However, its input bias current (260 nA) is three orders of magnitude higher than that of the original device (1 pA). This may introduce significant error in applications sensitive to input current, such as high-impedance signal sources or precision integrators. Additionally, its quiescent current (1.03 mA) is slightly higher than the original’s (820 µA), which should be considered in power‑critical designs. On the positive side, the LMV721M5X/NOPB offers higher bandwidth (10 MHz vs. 8 MHz) and slew rate (5.25 V/µs vs. 4.5 V/µs). Its input offset voltage (80 µV) is also substantially lower than the original’s (4.5 mV), which helps improve DC accuracy.
2. AD8515ARTZ‑REEL Substitution Conclusion
The AD8515ARTZ‑REEL, while package‑compatible (SOT‑23‑5) and supporting a wider low‑voltage range (1.8V to 5V), can be considered as a low‑power alternative to the TSV911ILT. Its quiescent current (410 µA) is only half that of the original device, making it suitable for battery‑powered equipment. The input bias current (5 pA), though higher than the original’s, remains extremely low and is adequate for most high‑impedance applications. Its bandwidth (5 MHz) and slew rate (2.7 V/µs) are both lower than those of the original part, which may limit performance in high‑frequency signal or fast‑transient response scenarios. Furthermore, its output current capability (20 mA) is relatively weak; driving low‑impedance loads requires careful evaluation.
