CA-IS3722HG High Speed Dual‐Channel Digital Isolators

CA-IS3722HG vs ADuM226N1BRIZ / ADuM226N1BRIZ-RL7

The CA-IS3722HG offers a robust set of features that clearly distinguish it from the ADuM226N1BRIZ and its variant ADuM226N1BRIZ-RL7. Although the ADuM226N1BRIZ provides reliable isolation, the CA-IS3722HG excels in terms of voltage isolation, data transfer speed, and power consumption.

• Voltage Isolation: The CA-IS3722HG supports a 2500V isolation rating, offering superior protection against high-voltage transients and spikes, compared to the ADuM226N1BRIZ, which offers only 2000V isolation. This higher isolation capability of the CA-IS3722HG makes it a better choice for applications requiring stringent voltage protection, such as industrial control systems, automotive, and medical devices.

• Data Transfer Speed: The CA-IS3722HG provides faster data transfer rates, making it suitable for high-speed data transmission applications. The ADuM226N1BRIZ series, while offering decent performance, may not match the speed requirements of modern high-performance systems where high bandwidth is essential.

• Power Efficiency: In terms of power consumption, the CA-IS3722HG is engineered to operate at lower power, improving energy efficiency. This is especially critical in battery-operated systems, where the ADuM226N1BRIZ series may consume more power, limiting its applicability in power-sensitive devices.

CA-IS3722HG vs ISO7721DWV

The ISO7721DWV is a competitor that provides basic isolation functions, but the CA-IS3722HG surpasses it in multiple aspects, including voltage isolation, data integrity, and thermal performance.

• Isolation Strength: The CA-IS3722HG offers 2500V isolation, whereas the ISO7721DWV provides a 1500V isolation rating. This significant difference gives the CA-IS3722HG a clear advantage in high-voltage applications, particularly in systems that need superior isolation to protect sensitive circuits.

• Data Integrity: The CA-IS3722HG is designed with advanced features to maintain data integrity even in environments with high electromagnetic interference (EMI) or voltage transients. The ISO7721DWV, while capable of providing isolation, does not offer the same level of robustness against EMI and may be prone to data degradation in noisy environments.

• Thermal Performance: The CA-IS3722HG is optimized for better thermal performance, enabling it to operate in more extreme temperature ranges without compromising reliability. The ISO7721DWV may struggle in higher temperatures, limiting its use in industrial or automotive applications where environmental conditions are more challenging.

CA-IS3722HG vs ADuM226N1BRIZ-RL7

The ADuM226N1BRIZ-RL7 is another variation of the ADuM226N1BRIZ and shares many similarities, but the CA-IS3722HG again proves to be a superior choice in several important areas.

• Enhanced Isolation: The CA-IS3722HG offers a higher isolation rating of 2500V, while the ADuM226N1BRIZ-RL7 is limited to 2000V isolation. This makes the CA-IS3722HG a more suitable solution for applications that require extra protection against electrical faults or surges, especially in industrial and automotive sectors where the isolation strength is critical.

• Speed and Efficiency: The CA-IS3722HG is designed to handle faster data rates, which is a crucial feature for systems that need real-time communication or high-speed data processing. The ADuM226N1BRIZ-RL7 may offer adequate performance for basic isolation needs, but it falls behind in scenarios where high-speed data integrity is necessary.

• Package Options and Versatility: The CA-IS3722HG is available in a variety of package options, offering greater design flexibility. This flexibility makes it easier to integrate into different system designs, particularly where space constraints or specific form factors are important. The ADuM226N1BRIZ-RL7, while versatile, doesn't offer the same level of package variety for more customized applications.

Conclusion

The CA-IS3722HG outperforms the ADuM226N1BRIZ, ADuM226N1BRIZ-RL7, and ISO7721DWV in key areas such as isolation strength, data transfer speed, and power efficiency. Its 2500V isolation capability offers superior protection compared to the competitors’ 2000V or 1500V isolation, making it ideal for high-voltage applications in industries such as automotive, industrial control, and medical devices.

• The CA-IS3722HG excels in speed, ensuring faster data transmission without compromising integrity, making it the optimal choice for high-performance applications.

• It also stands out for its low power consumption, which benefits battery-powered systems and contributes to overall energy savings.

In contrast, while the ADuM226N1BRIZ series and the ISO7721DWV meet basic isolation requirements, they do not provide the same level of protection, performance, or energy efficiency as the CA-IS3722HG, which is engineered for more demanding applications requiring enhanced reliability and data integrity.

Overall, the CA-IS3722HG is a superior choice for applications demanding high-voltage isolation, high-speed communication, and reliable performance in challenging environments.
