1. LM2904M8-13 Substitution Conclusion
The LM2904M8-13 can generally serve as a substitute for the LM358PWRG3, with two key differences to note: its input offset voltage is 2 mV (better than the original part’s 3 mV), which helps improve DC accuracy; however, its quiescent current is 700 µA per channel (higher than the original part’s 500 µA), leading to approximately 40% higher power consumption. Additionally, its supply voltage range is extended to 3–36 V (versus 3–30 V for the original part), offering wider operating flexibility, while the package change to an 8-MSOP (3.00 mm width) may affect PCB layout compatibility. If the application is power-sensitive or space-constrained, verify package compatibility. Other performance parameters such as bandwidth, slew rate, and output current are identical. Substitution is acceptable for general signal conditioning applications.
2. LM2904AM8-13 Substitution Conclusion
The LM2904AM8-13 is a superior alternative. It improves upon the LM2904M8-13 by further reducing input offset voltage to 1 mV (significantly better than the original part’s 3 mV), which substantially lowers DC error and makes it suitable for higher-precision applications. Its quiescent current remains 700 µA per channel (higher power consumption than the original part), while the supply voltage range (3–36 V) and package differences are the same as the LM2904M8-13. If the application can tolerate the increased power draw and the package is compatible, this device maintains the core performance of a general-purpose op-amp while offering higher input accuracy, making it a direct replacement in scenarios with stricter offset voltage requirements.
