ADUM3474WARSZ-RL7

Overview

The ADUM3474WARSZ-RL7 is a four-channel digital isolator from Analog Devices, housed in an SSOP-20 surface-mount package. It operates within a supply voltage range of 3 V to 5.5 V and supports bidirectional data transmission at speeds up to 25 Mb/s. The device provides 2500 Vrms isolation via magnetic coupling technology and features an integrated transformer driver. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates four independent bidirectional channels with internal transformer drivers for compact system design
• Utilizes on-chip silicon dioxide insulation and magnetic coupling for high-reliability signal isolation
• Meets AEC-Q100 qualification requirements suitable for demanding automotive electronic environments

Applications

• Automotive powertrain control systems requiring isolated communication
• Industrial motor drive gate drive interfaces
• Medical equipment signal isolation barriers

Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm that the component meets current RoHS directives and AEC-Q100 automotive grade specifications required by your application. Cross-reference the manufacturer part number against official Analog Devices documentation to ensure authenticity and correct revision status before integration into production designs.

Selection Notes

Select this component when four isolated bidirectional channels are required within a single package. It is appropriate for designs needing 2500 Vrms isolation with data rates up to 25 Mb/s. Consider the SSOP-20 footprint and operating temperature range of -40°C to +105°C against your board space and thermal constraints compared to other isolator families.

Part Context

This part belongs to the ADUM347x series of digital isolators. It shares architectural similarities with models like the ADUM3473 and ADUM3472 but differs in channel configuration or speed variants. The series utilizes proprietary iCoupler technology to replace traditional optocouplers, offering improved performance and smaller form factors for modern interface applications.
