ADM3260ARSZ-RL7

Overview

The ADM3260ARSZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates isolated DC-DC converters to provide power across the isolation barrier, supporting I2C bus communication with bidirectional data transfer at rates up to 1 Mb/s. The device operates on a supply voltage range of 3 V to 5.5 V and features a common-mode transient immunity of 25 kV/µs. Packaged in a 20-lead SSOP, it ensures electrical isolation with an insulation voltage rating of 2500 Vrms. The component supports thermal shutdown protection and functions reliably within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates isolated DC-DC converters to deliver power across the isolation barrier without external magnetics
• Supports bidirectional I2C communication with high-speed data transmission capabilities
• Provides robust signal isolation via iCoupler magnetic coupling technology
• Includes thermal shutdown protection for enhanced system reliability

Applications

• Industrial automation systems requiring isolated I2C interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Data acquisition systems with multi-channel sensor connections
• Power monitoring circuits requiring isolated communication buses

Procurement Notes

Verify the specific suffix RL7 corresponds to the reel packaging configuration required for your assembly line. Confirm that the 20-SSOP package dimensions align with your PCB footprint design. Ensure compatibility with the 3 V to 5.5 V supply rails used in your target application. Check for any recent lifecycle status updates or alternative recommendations from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when both signal isolation and integrated power delivery are required for I2C buses. It is suitable for designs where space constraints prevent the use of discrete transformers or optocouplers. Consider the 25 kV/µs CMTI rating for environments with high noise levels. Verify that the thermal performance meets the requirements of your specific enclosure and ambient temperature conditions.

Part Context

This part belongs to the ADM3260 series of IsoPower digital isolators. It combines analog and RF circuitry on silicon to create compact isolation solutions. The series is designed to replace traditional optocouplers and transformer-based isolators in modern electronic designs. It offers improved performance in terms of speed, size, and reliability compared to legacy technologies.

Replacement Considerations

Check for direct pin-compatible replacements within the ADM3260 family if different packaging options are needed. Evaluate ADUM3223ARZ-RL7 only if gate driver functionality is required instead of I2C isolation. Consult Analog Devices documentation for any recommended upgrades or end-of-life notifications regarding this specific part number.
