1. TSV851ICT Substitution Conclusion
From a core parameter perspective, the TSV851ICT offers slight advantages in bandwidth (1.3 MHz vs. 1 MHz) and minimum operating voltage (2.5V vs. 2.7V). However, its critical drawbacks are a significantly weaker output drive capability (70 mA vs. 160 mA) and a higher input offset voltage (4 mV vs. 1.7 mV). If the original circuit is intended to drive heavy loads (such as LEDs or small relays) or requires high DC precision, the TSV851ICT may not be a suitable direct replacement and could degrade performance. Conversely, for signal conditioning under light load conditions where precision is not critical, it can be considered as a substitute.
2. AZV321KSTR-G1 Substitution Conclusion
The AZV321KSTR-G1 shows high consistency with the original LMV321M7 part across most critical static and dynamic parameters, including gain bandwidth, slew rate, output current, supply range, and input offset voltage. However, its input bias current (250 nA) is substantially higher than that of the original (15 nA). In applications involving high-impedance signal sources or requiring high input impedance (e.g., sensor interfaces, integrator circuits), using the AZV321KSTR-G1 may introduce greater input current error, thereby affecting system accuracy. For general-purpose amplification or buffering circuits with lower source impedance or relaxed accuracy requirements, it serves as a viable direct replacement option.
