ADUM120N0WBRZ-RL7

Overview

The ADUM120N0WBRZ-RL7 is a two-channel digital isolator from Analog Devices, featuring an EMC robust design with a 3 kV isolation rating. It utilizes iCoupler technology for magnetic coupling and operates within a supply voltage range of 2.7 V to 5.5 V. The device supports data rates up to 150 Mb/s with a propagation delay of 10 ns. It functions in unidirectional mode (2/0 configuration) across an operating temperature range of -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it draws 3.1 mA of quiescent current.

Feature Summary

• Provides galvanic isolation between circuits using proprietary iCoupler magnetic technology
• Features enhanced electromagnetic compatibility robustness for noisy environments
• Supports high-speed digital signal transmission at rates up to 150 Mb/s
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits with high common-mode transient immunity requirements
• Automotive electronic modules demanding robust signal integrity

Procurement Notes

Verify the specific suffix WBRZ-RL7 against official Analog Devices documentation to confirm package type and reel quantity specifications. Confirm that the component meets all required environmental and electrical standards for your specific application before procurement. Check current availability status as distribution may be limited or subject to allocation constraints.

Selection Notes

Select this component when a dual-channel unidirectional isolator with high EMC performance is required. Ensure the 3 kV isolation rating aligns with system safety requirements. Verify that the 150 Mb/s data rate suffices for the target application speed. Consider the SOIC-8 footprint for PCB layout compatibility and thermal management needs.

Part Context

This part belongs to the ADUM120N series of digital isolators from Analog Devices. The series is characterized by its use of silicon dioxide insulation layers and copper coils for signal transmission. These devices are designed to replace traditional optocouplers in applications requiring higher reliability, lower power consumption, and better performance consistency over temperature and time.

Replacement Considerations

Consult Analog Devices official substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Do not assume functional equivalence with other channel counts or isolation voltages without explicit manufacturer confirmation.
