1. LMV358IPT Substitution Conclusion
The LMV358IPT is not a viable direct substitute. Although both are dual-channel rail-to-rail output op-amps with similar packages, key parameters differ significantly: the LMV358IPT’s quiescent current (162 μA) is 1.25 × that of the TLV2313 (65 μA/channel, totaling ~130 μA), resulting in a clear power consumption disadvantage. Its input bias current (16 nA) is four orders of magnitude higher than that of the TLV2313 (1 pA), which would introduce substantially larger input errors in applications requiring high input impedance, handling weak currents, or interfacing with high-impedance signal sources (e.g., sensor interfaces), severely degrading accuracy. Additionally, its minimum supply voltage is 2.7 V, unable to cover the 1.8 V low-voltage operation of the TLV2313. Substitution should only be considered in non‑critical scenarios where power consumption, input error, and low‑voltage supply are not concerns.
2. TS1852IST Substitution Conclusion
The TS1852IST can serve as a substitute with limitations and requires careful evaluation. Its advantages include a quiescent current (162 μA) in the same micropower range as the TLV2313 (~130 μA total) and a supply voltage range (1.8 V–6 V) that fully covers the original part. The main drawbacks are reduced precision and speed: its input offset voltage (1 mV) is considerably higher than that of the TLV2313 (750 μV), degrading DC accuracy and potentially requiring additional calibration or nulling in the application. Moreover, its gain‑bandwidth product (630 kHz) and slew rate (0.25 V/µs) are both lower than those of the original (1 MHz, 0.5 V/µs), resulting in narrower signal‑processing bandwidth and slower large‑signal response. This substitute is suitable only for low‑frequency, DC micropower signal‑conditioning applications where high precision and speed are not critical.
