LTM2882IY-3

Overview

The LTM2882IY-3#PBF is a complete galvanically isolated dual RS-232 μModule transceiver manufactured by Analog Devices. It integrates two drivers and two receivers within a BGA-32 package, supporting data rates up to 10 Mb/s with half-duplex communication. The device operates on a supply voltage range of 3 V to 3.6 V and draws 24 mA of operating current. It features high ESD protection rated at 10 kV and an output short-circuit current capability of 200 mA. The module includes shutdown functionality and maintains signal propagation delay of 0.2 µs across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates dual isolated RS-232 transceivers and power management in a single compact module without requiring external components
• Provides galvanic isolation for robust signal transmission in electrically noisy environments
• Includes built-in ESD protection and shutdown control for enhanced system reliability

Applications

• Industrial automation systems requiring isolated serial communication
• Medical equipment needing safe patient connection interfaces
• Test and measurement instruments demanding high noise immunity

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS status before procurement. Confirm the BGA-32 package type matches your PCB footprint requirements. Ensure the 3 V to 3.6 V supply voltage aligns with your system design. Check moisture sensitivity levels for proper storage and reflow soldering procedures. Validate that the 10 Mb/s data rate meets your application's throughput needs.

Selection Notes

Select this component when a compact, fully integrated solution for dual isolated RS-232 links is required. It eliminates the need for separate isolators and charge pumps, simplifying board layout. Consider the BGA-32 package constraints during mechanical design. Verify that the 24 mA quiescent current fits your power budget. Ensure the -40°C to +85°C operating range covers your environmental conditions.
