LTM2882CV-5#PBF

Overview

The LTM2882CV-5#PBF is a complete galvanically isolated dual RS-232 μModule transceiver manufactured by Analog Devices Inc. It integrates two drivers and two receivers within a single LGA-32 package, supporting data rates up to 10 Mb/s in half-duplex mode. The device operates with a single 5V supply, drawing 17 mA of working current, and dissipates 85 mW of power. It provides 10 kV ESD protection and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Integrates dual isolated RS-232 transceivers with an integrated power module, eliminating the need for external components.
• Provides galvanic isolation between the logic side and the serial port side to protect sensitive electronics.
• Features high electromagnetic interference immunity and robust electrostatic discharge protection.

Applications

• Industrial control systems requiring isolated serial communication
• Medical equipment needing safe patient isolation interfaces
• Test and measurement instruments with ground loop prevention requirements

Procurement Notes

Verify the specific suffix CV against the official datasheet to confirm the package type and thermal characteristics match the design requirements. Confirm that the 5V operating voltage aligns with the system power rails. Ensure the LGA-32 footprint matches the PCB layout constraints. Check for any recent product change notifications regarding material or manufacturing site updates.

Selection Notes

Select this component when a compact solution for dual-channel isolated RS-232 communication is required without external magnetics or capacitors. It is suitable for designs prioritizing board space reduction and simplified BOM management. Consider the 10 Mb/s speed limit and half-duplex operation when evaluating protocol compatibility. Verify that the 2500VRMS isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the LTM2882 series of μModule isolators from Analog Devices. These devices combine the transceiver and power conversion functions into a single micromodule. The series is designed to simplify the design-in process for isolated serial interfaces by removing the complexity associated with discrete isolation components.

Replacement Considerations

Consult the official Analog Devices cross-reference guide for verified substitutes. Ensure any replacement maintains the LGA-32 package dimensions and pinout configuration. Verify that alternative parts support the same 5V supply voltage and isolation voltage ratings.
