1. LM2904DT Substitution Conclusion
The LM2904DT is not a direct replacement for the OP213ESZ due to significant performance gaps that can degrade system precision, bandwidth, and output dynamic range. The key differences are: its input offset voltage (2 mV vs. 100 µV) is an order of magnitude higher, severely degrading DC accuracy and making it unsuitable for precision amplification or signal conditioning; its gain bandwidth product (700 kHz vs. 3.4 MHz) and slew rate (0.6 vs. 1.2 V/µs) are both lower, limiting circuit response to high-frequency or fast transient signals; its output stage is single-ended rather than rail-to-rail, preventing the output voltage from swinging close to the supply rails, which reduces usable signal swing and is particularly problematic in low-voltage applications.
2. LM358DT Substitution Conclusion
The LM358DT is likewise not a direct substitute for the OP213ESZ. Its performance limitations are similar to the LM2904DT, with some minor variations. It shares the drawbacks of high input offset voltage (2 mV) and low slew rate (0.6 V/µs), resulting in insufficient DC accuracy and speed performance. While its gain bandwidth product (1.1 MHz) is slightly higher than that of the LM2904DT, it remains well below the original part, limiting high-frequency capability. Its output stage is not specified as rail-to-rail and typically behaves as single-ended, similarly constraining output dynamic range. Its only potential advantage is AEC-Q100 automotive-grade qualification. In applications where reliability standards are critical and performance degradation is acceptable, it could serve as a rugged, lower-performance alternative. However, it is not recommended for substitution in most scenarios where electrical performance is a priority.
