1. BA4580RFVM-TR Substitution Conclusion
The BA4580RFVM-TR can partially replace the LM358ST in terms of key parameters; however, its high power consumption (6mA total current vs. 1.4mA) and higher input bias current (100nA vs. 20nA) are primary limitations. Advantages include a higher slew rate (5V/µs) and gain-bandwidth product (5MHz), making it suitable for applications requiring fast response or wideband signal processing. Nevertheless, the significantly increased quiescent current may render it unsuitable for battery-powered or low-power designs. The higher input bias current could also affect precision in high-impedance sensing circuits. Additionally, while its operating voltage range (4–32V) is compatible with the LM358ST’s 3–30V range, it lacks AEC-Q100 automotive-grade qualification. If the original design is intended for automotive electronics, reliability must be re-evaluated.
2. BA4560FVM-GTR Substitution Conclusion
The BA4560FVM-GTR is limited by its relatively high minimum operating voltage (8V vs. 3V), preventing direct use in low-voltage systems such as those powered by a single 3.3V or 5V supply. Its advantages include a higher gain-bandwidth product (10MHz) and moderate power consumption (4mA). The slew rate (4V/µs) is also notably better than that of the LM358ST, making it suitable for medium-to-high-speed signal processing. Parameters such as input bias current (50nA) and offset voltage (500µV) are moderate, though the quiescent current remains approximately three times that of the LM358ST. If the original circuit operates at a supply voltage ≥8V and is not power-sensitive, substitution may be considered. However, the device similarly lacks automotive-grade certification, and its output current capability (25mA) is relatively low—load drive requirements must be verified for compatibility.
