ADUM3200WBRZ-RL7

Digital Isolators Overview

The ADUM3200WBRZ-RL7 is a bidirectional digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features two independent channels with a data rate of 25 Mb/s and a propagation delay of 45 ns. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing 7.7 mA of working current. It provides an isolation voltage of 2500 Vrms and meets AEC-Q100 automotive qualification standards. Packaged in an SOIC-8 surface-mount format, it supports an operating temperature range from -40°C to +105°C.

Digital Isolators Feature Summary

• Enhanced system-level electrostatic discharge (ESD) reliability for robust signal integrity.
• Bidirectional data transmission capability across two isolated channels.
• High common-mode transient immunity ensuring stable operation in noisy environments.

Digital Isolators Applications

• Automotive electronic control units requiring AEC-Q100 compliance
• Industrial communication interfaces such as RS-485 and CAN bus
• Medical equipment needing high isolation safety standards

Digital Isolators Procurement Notes

Verify the specific suffix 'W' indicates enhanced ESD performance compared to standard variants. Confirm the '-RL7' designation matches the required reel packaging quantity of 1000 units. Ensure the SOIC-8 package width aligns with PCB footprint constraints. Cross-reference the datasheet revision date to confirm compatibility with latest design guidelines.

Digital Isolators Selection Notes

Select this component when bidirectional communication is required at speeds up to 25 Mb/s. The 2500 Vrms isolation rating suits applications demanding significant potential difference between circuits. The wide operating temperature range makes it suitable for harsh industrial or automotive environments. Consider the 7.7 mA current consumption against power budget requirements.

Digital Isolators Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the SOIC-8 package and core magnetic coupling architecture with other members like the ADUM3200BRZ. The 'W' variant specifically differentiates itself through improved ESD characteristics while maintaining identical electrical parameters and pinout configurations.

Digital Isolators Replacement Considerations

ADUM3200BRZ serves as a direct functional substitute within the same family, differing primarily in ESD specifications rather than core electrical performance.
