ADM3251EARWZ-REEL

Overview

The ADM3251EARWZ-REEL is a high-speed, fully isolated single-channel RS-232 transceiver from Analog Devices. It integrates an IsoPower DC/DC converter, allowing operation from a single 5V supply while providing 2500Vrms isolation between channels. The device supports data rates up to 460Kbps with a common-mode transient immunity of 25kV/µs. It features propagation delays of 135ns and 190ns, and operates within a temperature range of -40°C to 85°C. Packaged in a 20-SOIC surface-mount format, it includes ESD protection on input and output pins.

Feature Summary

• Integrates an isolated DC/DC converter for single-supply operation
• Provides complete galvanic isolation for power and data signals
• Includes integrated ESD protection on driver inputs and receiver outputs

Applications

• Industrial communication systems
• Medical equipment diagnostic ports
• General-purpose RS-232 data links

Procurement Notes

Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm that the component meets RoHS3 compliance standards for your region. Ensure the voltage rating aligns with system requirements. Check for any specific automotive or industrial certifications if applicable to the end product.

Selection Notes

Select this component when full isolation of both power and data is required from a single voltage source. It is suitable for noisy environments due to high CMTI ratings. Consider the 20-SOIC footprint for PCB layout constraints. Evaluate the 460Kbps speed against application needs.

Part Context
