LTM2882CY-5#PBF

Overview

The LTM2882CY-5#PBF is a complete galvanically isolated dual RS-232 μModule transceiver manufactured by Analog Devices Inc. It integrates two independent transmitters and receivers with integrated power supplies in a single package, eliminating the need for external components. The device operates on a single 5V supply and provides 2500VRMS isolation between the logic side and the RS-232 side. It supports data rates up to 1 Mbps and features a BGA-32 package.

Feature Summary

• Integrates dual RS-232 transceivers with isolated power supplies in a compact module
• Provides galvanic isolation between logic and serial interface domains
• Requires no external discrete components for operation
• Supports standard RS-232 voltage levels and signaling

Applications

• Industrial communication systems requiring isolated serial interfaces
• Medical equipment needing patient isolation protection
• GPS navigation systems with isolated data links
• Point-of-sale (POS) terminals with secure communication channels

Procurement Notes

Verify the specific suffix CY-5#PBF against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with DC1747A-B demonstration boards if evaluation is required. Confirm RoHS compliance status through current manufacturer datasheets before procurement.

Selection Notes

Select this component when a compact, fully integrated solution for dual isolated RS-232 communication is needed. It is suitable for designs where board space is limited and external isolation components are undesirable. Consider the 1 Mbps data rate limit and 2500VRMS isolation rating against system requirements.

Part Context

This part belongs to the LTM2882 series of μModule isolators from Analog Devices. These modules combine magnetic isolation technology with power management to provide robust signal integrity in noisy environments. The series offers various configurations for different isolation voltages and channel counts.

Replacement Considerations

The LTM2882CV-5#PBF is a related variant using an LGA-32 package instead of BGA-32. Verify pinout compatibility and thermal performance differences before substitution. Other series members like LTM2883 offer higher channel counts but may require different design adjustments.
