ADUM3300WBRWZ-RL

Overview

The ADUM3300WBRWZ-RL is a three-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an insulation voltage of 2500 Vrms and features bidirectional channel polarity. Key electrical parameters include a propagation delay of 32 ns and a typical operating supply current of 69 mA. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Employs magnetic coupling isolation technology for robust signal transmission
• Supports bidirectional data flow across all three channels
• Meets automotive qualification requirements via AEC-Q100 certification

Applications

• Automotive electronic control units requiring isolated communication
• Industrial systems with high common-mode transient immunity needs
• Medical equipment demanding galvanic isolation between circuits

Procurement Notes

Verify the specific suffix WBRWZ-RL against official Analog Devices documentation to confirm package type and reel configuration. Ensure compatibility with system voltage levels and thermal management requirements before integration. Cross-reference the AEC-Q100 qualification status with project specifications to validate automotive suitability. Confirm lead times and availability through authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a three-channel isolator with bidirectional capability is required. Consider the 90 Mb/s data rate limit for high-speed applications. Evaluate the 2500 Vrms insulation rating against system safety standards. Compare power consumption characteristics with alternative isolators if battery life is critical. Verify SOIC-16 footprint compatibility during PCB layout design.

Part Context

This part belongs to the ADUM3300 series of digital isolators manufactured by Analog Devices Inc. It is designed for general-purpose isolation in mixed-signal environments. The series leverages iCoupler technology to provide compact, low-power solutions. It serves as a replacement for traditional optocouplers in many industrial and automotive applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADUM3300 family. Verify that substitute parts maintain the same 2500 Vrms insulation rating and AEC-Q100 qualification. Ensure data rate and propagation delay specifications meet or exceed original requirements.
