ADM3252EABCZ

Overview

The ADM3252EABCZ is a dual-channel, fully isolated RS-232 transceiver utilizing Analog Devices' iCoupler technology. It integrates magnetic coupling for signal isolation and isoPower for on-chip power conversion, eliminating external transformers. The device operates from a single 3V to 5.5V supply with a data rate of 460 kb/s and 2500 Vrms insulation voltage. Packaged in a BGA-44, it supports unidirectional transmission within a -40°C to +85°C range.

Feature Summary

• Integrates dual-channel signal isolation and isolated power generation via iCoupler technology
• Eliminates the need for external discrete components or bulky transformers
• Provides robust electrical isolation between RS-232 interfaces and host systems

Applications

• Isolated USB to RS-232/RS-485 interface bridges
• Industrial bus traffic monitoring systems
• PC communication ports lacking native RS-232 connectivity

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Ensure the BGA-44 package matches your PCB footprint design specifications.

Selection Notes

Select this component when high-density integration of isolated RS-232 communication is required. It is suitable for designs needing compact form factors without sacrificing isolation performance. Consider thermal dissipation limits and operating temperature ranges for industrial environments.

Part Context

This part belongs to the ADM3252E series of digital isolators. It represents an evolution in interface ICs by combining transceiver functions with isolation barriers. The series targets applications demanding reliable data transmission across galvanic boundaries in noisy environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADM3252 family. Verify that substitute parts maintain identical isolation voltage ratings and data speed capabilities before implementation.
