1. LM2904PW Substitution Conclusion
Overall, the LM2904PW can serve as a functional substitute for the original LM2904ATH-13, with several key differences requiring attention. The input offset voltage increases from the original 1 mV to 3 mV, which may introduce greater error in precision amplification or DC-coupled applications, thereby affecting signal accuracy. The maximum supply voltage is reduced from 36 V to 26 V, limiting its suitability in high-voltage environments such as industrial power systems. The supply current decreases from 700 µA to 500 µA, contributing to lower power consumption and improved energy efficiency. All other parameters, including package, bandwidth, and output current, remain identical. The LM2904PW is a viable alternative for applications where offset voltage sensitivity is low and the supply voltage does not exceed 26 V.
2. LM358PW Substitution Conclusion
In general, the LM358PW is a feasible substitute for the original LM2904ATH-13, with performance characteristics similar to the LM2904PW but offering slight improvements in certain areas. Notably, its input offset voltage is also 3 mV (higher than the original 1 mV), which may degrade performance in high-precision applications. The maximum supply voltage is 30 V, higher than the LM2904PW's 26 V but still below the original 36 V, making it more suitable for medium-voltage range applications while unable to cover 36 V high-voltage scenarios. The supply current is 500 µA (lower than the original 700 µA), which is beneficial for power savings. Other parameters such as package, bandwidth, and output current remain consistent. The LM358PW can replace the original part in applications where the supply voltage does not exceed 30 V and offset voltage requirements are not stringent.
