1. LM2904AS-13 Substitution Conclusion
The LM2904AS-13 is a direct functional and pin-compatible replacement for the original part. Key parametric differences are as follows: it offers a lower input offset voltage (1mV vs. 3mV), resulting in improved DC accuracy; the quiescent current is slightly higher (700µA vs. 500µA), leading to a modest increase in power consumption; and the operational supply voltage range has a higher upper limit (36V vs. 26V), enhancing its suitability for higher-voltage systems. In summary, this device is a viable substitute for general-purpose applications where ultra-low power consumption is not critical and where the benefits of higher voltage tolerance and improved precision are advantageous. However, the impact of its increased power draw on the overall system should be evaluated.
2. LM2904AQS-13 Substitution Conclusion
The LM2904AQS-13 also maintains direct drop-in compatibility. In addition to sharing the improvements of the LM2904AS-13—such as a wider supply voltage range (36V max) and higher quiescent current (700µA)—it features a lower input offset voltage (2mV vs. 3mV) and a wider lower supply voltage limit (2V vs. 3V). This grants it superior startup and operational capability under low-voltage supply conditions. Furthermore, it is AEC-Q100 qualified, meeting the reliability and extended temperature range requirements for demanding environments like automotive electronics. For applications requiring a wide voltage range, automotive-grade reliability, or enhanced low-voltage performance, this part represents a superior alternative. The only consideration remains its higher power consumption compared to the original part.
