1. LT2079CSPBF Substitution Conclusion
Direct substitution is not recommended. The core deficiencies of the LT2079CS lie in its extremely low bandwidth (GBW: 200 kHz vs. 12 MHz) and very slow slew rate (0.07 V/µs vs. 2.7 V/µs). It is completely incapable of handling mid-to-high frequency signals or fast transient signals that the original part can manage, representing a severe deficiency in dynamic performance. Its advantage is an ultra-low quiescent current (47 µA vs. unspecified), but its input offset voltage (80 µV vs. 40 µV) is slightly worse. It is only suitable for applications that are extremely power-sensitive and involve very low signal frequencies (e.g., DC or sub-audio). It is not viable as a substitute for high-speed applications.
2. LM324ADR2G Substitution Conclusion
Direct substitution is not recommended; it may be cautiously evaluated only in non-critical, low-cost applications. The primary shortcomings of the LM324ADR2G are its low bandwidth (GBW: 1 MHz vs. 12 MHz) and very high input offset voltage (2 mV vs. 40 µV). The former severely limits signal processing frequency, while the latter introduces significant accuracy errors in DC or precision amplification applications. Its advantages are a stronger output drive current (40 mA vs. 10 mA) and a wider supply voltage range (3-32V vs. 10-30V). It cannot replace the original part in applications requiring any meaningful speed or precision. It can only be considered for general-purpose circuits with very low bandwidth and accuracy requirements but needing stronger output drive or single-supply operation.
