ADUM1223BRWZ

Overview

The ADUM1223BRWZ is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology to provide electrical isolation between circuits. It features two independent channels with unidirectional data transmission capability. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 150 Mbps. Key electrical parameters include a propagation delay of 7.2 ns maximum, rise and fall times of 2.5 ns typical, and a common-mode transient immunity of 75 kV/µs. It is housed in a 16-lead SOIC package and rated for operation from -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation using proprietary iCoupler magnetic coupling technology without requiring external components.
• Supports high-speed data transmission with low propagation delay and minimal pulse width distortion for precise timing applications.
• Features high common-mode transient immunity to maintain signal integrity in electrically noisy environments.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Automotive electronics for noise-resistant data links

Procurement Notes

Verify the specific suffix BRWZ corresponds to the tube packaging variant when sourcing. Confirm that the required channel count and unidirectional configuration match the application design before procurement. Ensure compatibility with the target logic voltage levels and thermal management requirements for the operating environment.

Selection Notes

Select this component when dual-channel isolation is required with high speed and low latency. Compare against single-channel variants if only one link is needed. Consider the 16-lead SOIC footprint constraints and verify that the 75 kV/µs CMTI meets the system's noise rejection specifications compared to lower-immunity alternatives.

Part Context

The ADUM1223BRWZ belongs to the ADuM12xx family of dual-channel digital isolators designed for cost-effective isolation solutions. It shares architectural similarities with other members like the ADUM1221 but differs in channel count and specific performance metrics such as propagation delay and power consumption profiles within the same package type.
