1. LMH6724MA/NOPB Substitution Conclusion
The LMH6724MA/NOPB can generally substitute the LT1396CS8 in key parameters; however, its slightly lower bandwidth (370MHz vs. 400MHz) and slew rate (600V/µs vs. 800V/µs) may affect precision in very high‑frequency signal response. Its advantages include a quiescent current of only 1mA per channel (versus 4.6mA for the LT1396), resulting in significantly lower power consumption, and a higher output current (110mA), making it more suitable for low‑power or moderately loaded drive applications. The minimum supply voltage (4.5V) is slightly higher than that of the original part (4V); system minimum voltage compatibility should be verified. If the application does not demand extreme bandwidth or slew rate and prioritizes power efficiency, the LMH6724 can be considered a valid substitute.
2. OPA2674IDG4 Substitution Conclusion
The OPA2674IDG4 offers a differentiated substitution profile in terms of dynamic performance: its slew rate reaches 2000V/µs, far exceeding the LT1396’s 800V/µs, making it suitable for high‑speed transient signal processing. However, its –3dB bandwidth (260MHz) is lower, which may limit performance with high‑frequency continuous signals. With an output current of 500mA, it provides strong drive capability for heavy loads such as cable driving, but the quiescent current increases to 18mA per channel, leading to substantially higher power consumption. The minimum supply voltage is raised to 5V, requiring assessment of power supply compatibility. If the application emphasizes high‑speed, high‑current drive over wide bandwidth and can tolerate higher power dissipation, the OPA2674 may serve as a substitute in specific scenarios.
