1. TSV852IYST Substitution Conclusion
The TSV852IYST should be carefully evaluated as a substitute and is only viable under specific conditions. Key differences include: a significantly higher input bias current (27 nA vs. 4 pA), which may introduce considerable error in high-impedance signal sources or precision integrator circuits; quiescent current is approximately 2.9 times higher (130µA vs. 45µA), making it unsuitable for battery-powered ultra-low-power applications. However, advantages include higher output drive capability (70 mA vs. 30 mA), a wider minimum supply voltage (2.3 V vs. 2.7 V), and AEC-Q100 automotive qualification. Substitution may be acceptable if the application is not sensitive to input leakage current, requires stronger output or automotive-grade reliability, and can tolerate increased power consumption.
2. LMV358LIPT Substitution Conclusion
The LMV358LIPT is generally acceptable as a replacement, but key performance trade-offs must be considered. Primary differences from the original part are: similarly higher input bias current (27 nA vs. 4 pA), making it unsuitable for weak current amplification applications such as photodetection; quiescent current is also notably higher (130µA vs. 45µA), impacting low-power designs. Advantages include higher gain bandwidth product (1.3 MHz vs. 1 MHz) and output current (70 mA vs. 30 mA), while input offset voltage (1 mV) remains consistent with the original part and the package is compatible. Direct substitution is feasible if the application does not require extremely low input bias current and the increased power consumption is acceptable in exchange for improved performance.
