1. LM2904M8-13 Substitution Conclusion
The LM2904M8-13 can be used as a replacement for the LM358PW, but differences in certain performance parameters and application conditions should be considered. Key distinctions include: a lower input offset voltage (2 mV vs. 3 mV), which improves DC accuracy; a slightly higher quiescent current (700 µA vs. 500 µA per channel), potentially leading to a minor increase in power consumption; a higher supply voltage rating (36 V vs. 30 V), allowing operation over a wider voltage range; and a narrower 8-MSOP package (3.00 mm width), requiring verification of PCB layout compatibility. In low-power-sensitive applications, the impact of the higher current draw should be evaluated. However, the higher voltage tolerance and improved offset voltage may make it a better performer in applications requiring wider supply ranges or slightly higher precision.
2. LM2904AM8-13 Substitution Conclusion
The LM2904AM8-13 is a preferred substitute for the LM358PW, with further optimized key specifications. Compared to the original part, it offers a significantly lower input offset voltage (1 mV vs. 3 mV), substantially reducing DC error; its quiescent current remains 700 µA per channel, which is slightly higher than that of the LM358PW; the maximum supply voltage is extended to 36 V, providing greater supply headroom; and it uses the same narrow-body 8-MSOP package, so mechanical compatibility must be confirmed. These enhancements make this device clearly advantageous for replacement in applications demanding high DC accuracy and wide supply voltage operation. However, if the application is extremely sensitive to microamp-level power consumption, the impact of the increased quiescent current should be carefully assessed.
