1. THS4022CD Substitution Conclusion
Based on a comparison of key parameters, the THS4022CD significantly outperforms the AD828ARZ in bandwidth (350MHz vs. 130MHz) and slew rate (470V/µs vs. 450V/µs). It also offers higher output current drive (100mA vs. 50mA) and slightly lower power consumption (7.8mA/channel vs. 14mA total supply current). However, its operational voltage range is narrower (9V to 32V vs. 5V to 36V). This makes it unsuitable for direct substitution in low-voltage single-supply (≤5V) or high-voltage (>32V) applications. If the system supply voltage falls within the 9V to 32V range and requires higher bandwidth and output drive capability, the THS4022CD can serve as a performance upgrade alternative. Care must be taken to evaluate the impact of subtle parameter differences, such as input bias current, on precision circuits.
2. THS4032CDR Substitution Conclusion
The THS4032CDR has lower bandwidth (100MHz) and slew rate (100V/µs) compared to the AD828ARZ (130MHz, 450V/µs). While its output current capability is similar (90mA vs. 50mA), its dynamic performance is notably weaker. This may be insufficient for high-frequency or fast transient response applications, such as video signal processing. Its voltage range is similarly limited (9V to 32V), and its power consumption is comparable to the original part. The THS4032CDR is only suitable for medium- to low-speed applications with relaxed bandwidth and slew rate requirements. If the original design relies on the AD828's high-frequency characteristics, a direct substitution will degrade performance, necessitating a re-evaluation of system stability and signal integrity.
