ADM3260ARSZ

Overview

The ADM3260ARSZ is a dual-channel I2C digital isolator from Analog Devices, featuring integrated IsoPower DC-DC converters. It operates within a 3 V to 5.5 V supply range and supports data rates up to 1 Mb/s. The device provides 2500 Vrms isolation voltage and a common-mode transient immunity of 25 kV/µs. Packaged in a 20-SSOP, it functions across an operating temperature range of -40°C to +105°C with a typical propagation delay of 340 ns.

Feature Summary

• Integrates isolated power supplies via on-chip DC-DC converters for simplified design
• Supports bidirectional I2C communication protocols with hot-swappable capability
• Provides high common-mode transient immunity for reliable signal integrity

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment interfaces needing safety-certified isolation
• Automotive sensor modules demanding robust noise rejection

Procurement Notes

Verify the specific suffix ARSZ corresponds to the SSOP-20 tube packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly line standards. Ensure the supplier provides valid traceability documentation for this Analog Devices component to maintain quality assurance protocols during procurement.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a single package. It is suitable for designs where board space is limited and external isolated power supplies are undesirable. Consider the 20-pin footprint and thermal dissipation characteristics relative to your enclosure constraints and ambient operating conditions.

Part Context

This part belongs to the ADM3260 series, which utilizes iCoupler magnetic coupling technology. It is designed specifically for I2C bus applications, distinguishing itself from general-purpose digital isolators by integrating the necessary power conversion circuitry directly on the silicon die.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family that may offer different packaging options or updated revision statuses. Verify if newer generations provide enhanced CMTI ratings or modified pin assignments before substituting.
