1. LMH6724MAX/NOPB Substitution Conclusion From the perspective of key parameters and package compatibility, the LMH6724MAX/NOPB can serve as a substitute for the LT1396CS8TRPBF, offering comparable or superior performance in most applications. However, it is important to note a slight reduction in speed performance. The key differences are as follows: The LMH6724 features a significantly lower quiescent current (1 mA per channel) compared to the LT1396 (4.6 mA per channel), resulting in substantially lower system power consumption post-substitution. This makes it more suitable for power-sensitive designs. Its output current capability (110 mA) is higher than that of the LT1396 (80 mA), providing better drive capability for capacitive or low-impedance loads. The slew rate (600 V/µs) and bandwidth (370 MHz) of the LMH6724 are slightly lower than those of the LT1396 (800 V/µs, 400 MHz). In ultra-high-frequency applications demanding extreme signal slope or bandwidth, the LT1396 retains an advantage. Additionally, the LMH6724 has a slightly higher minimum operating voltage (4.5V) compared to the LT1396 (4V). In scenarios with extremely low supply voltages, voltage headroom must be verified. In summary, the substitution maintains functional and package compatibility while achieving lower power consumption. However, if the application has stringent requirements for slew rate and bandwidth, circuit performance should be validated to ensure it still meets the required specifications.
