1. ADM3072EYRZ-REEL7 Substitution Conclusion
The ADM3072EYRZ-REEL7 has low feasibility as a direct replacement, primarily due to its maximum data rate of 250 kbps, which is significantly lower than the original LTC2850HS8TRPBF’s 20 Mbps. If the original application involves high-speed communication—such as in industrial automation or high-speed data acquisition—the substitute will fail to meet bandwidth requirements, potentially causing communication delays or failures. Additionally, the receiver hysteresis has increased from 25 mV to 100 mV. While this improves noise immunity and makes the device suitable for noisy environments, it may reduce sensitivity to weak signals and compromise signal integrity. Substitution is not recommended unless the application’s data rate requirement is below 250 kbps and noise immunity is a higher priority.
2. ADM3075EYRZ-REEL7 Substitution Conclusion
The ADM3075EYRZ-REEL7 also offers limited substitution feasibility. Its data rate of 500 kbps, though higher than that of the ADM3072EYRZ-REEL7, remains well below the original part’s 20 Mbps. In applications requiring high-speed transmission, this substitute would create a performance bottleneck, leading to reduced data throughput. The receiver hysteresis is likewise 100 mV, matching the ADM3072EYRZ-REEL7. This enhances noise margin but trades off some signal response speed. Substitution may only be viable if the application’s data rate does not exceed 500 kbps and the operating environment is particularly noisy; otherwise, the high-speed capability of the original part should take precedence.
