1. THS3112IDDA Substitution Conclusion
From a key parameter perspective, the THS3112IDDA offers an extremely high slew rate (1550 V/µs) and strong output current capability (270 mA). However, its -3dB bandwidth (110 MHz) is slightly lower than that of the HA5023IBZ (125 MHz), and its supply voltage range (10 V to 30 V) differs from the original part's ±4.75 V to ±18 V. The THS3112 demonstrates superior performance in high-speed, high-current drive applications, such as driving capacitive loads. Nevertheless, its slightly lower bandwidth may affect high-frequency signal fidelity, and its supply design requires re-adaptation. Substitution is viable if system bandwidth requirements are not stringent and higher power consumption is acceptable.
2. LMH6724MAX/NOPB Substitution Conclusion
The LMH6724MAX/NOPB significantly outperforms the HA5023IBZ in both bandwidth (370 MHz) and slew rate (600 V/µs), while maintaining a very low quiescent current (1 mA per channel). However, its supply voltage range (4.5 V to 12 V) is narrower than the original part's, and its output current (110 mA), although higher than the original, is lower than that of the THS3112. This device excels in high-bandwidth, low-power applications and is particularly suitable for portable or high-frequency signal processing systems. Direct substitution is not feasible if the original design relies on higher supply voltages (e.g., ±15 V); power supply compatibility must be evaluated.
