ADUM1402BRWZ-RL

Overview

The ADUM1402BRWZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with a data rate of 10Mbps and 25kV/µs common-mode transient immunity. The device operates on a 2.7V to 5.5V supply, features unidirectional channels in a 16-SOIC package, and supports an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air-core transformer technology for high-speed signal transmission.
• Provides robust electrical isolation with specified voltage ratings and high common-mode transient immunity to protect sensitive circuitry.
• Supports standard CMOS logic levels with low propagation delay and pulse width distortion for precise timing applications.

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal conditioning circuits
• Automotive electronic control unit (ECU) data lines

Procurement Notes

Verify the specific suffix Z and RL against official Analog Devices documentation to confirm RoHS compliance and tape-and-reel packaging configuration. Ensure the component status matches current manufacturing schedules as older variants may be obsolete. Cross-reference the datasheet revision date to validate technical parameters before integration into designs.

Selection Notes

Select this component when four isolated bidirectional or unidirectional channels are required within a single package. Compare performance metrics such as propagation delay and power consumption against alternative isolators. Confirm that the 16-SOIC footprint and thermal characteristics align with the target PCB layout constraints and environmental operating conditions.

Part Context

This part belongs to the ADuM140x series of quad-channel digital isolators. It represents a transition from traditional optocouplers to silicon-based isolation solutions. The BRWZ-RL designation indicates a specific manufacturing lot, lead-free composition, and reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

ADUM1402BRWZ is a verified substitute offering identical functionality in tube packaging. Verify pinout compatibility and electrical specifications before substitution. Check manufacturer announcements for end-of-life notices regarding the original part number.
