1. LMV358ID Substitution Conclusion
The LMV358ID can generally replace the original LMV358SG-13 in most universal applications, with two notable differences: first, the supply current increases from 190 µA to 210 µA per channel, which will slightly raise system power consumption in battery‑operated or low‑power designs and may reduce battery life; second, the output current drops from 90 mA to 40 mA per channel, effectively halving the drive capability. This reduction may be insufficient for high‑current loads such as directly driving relays, motors, or high‑power LEDs. If the target circuit does not demand high output current—as in signal conditioning, sensor interfaces, or other light‑load scenarios—and can tolerate the marginally higher quiescent current, substitution is acceptable. Otherwise, the load requirements should be re‑evaluated.
2. LMV358QD Substitution Conclusion
The LMV358QD exhibits identical substitution characteristics to the LMV358ID, as both share the same electrical parameters. Compared with the original LMV358SG‑13, the differences remain: supply current rises from 190 µA to 210 µA per channel, and output current decreases from 90 mA to 40 mA per channel. When substituting, the system will experience a slight increase in power consumption and a significant reduction in output drive capability. The latter is particularly critical: if the original design relies on high output current to drive the load, substitution may lead to inadequate performance or failure. Conversely, in low‑load applications where cost or supply‑chain flexibility is prioritized, substitution can be considered acceptable, provided the overall power budget is verified.
