LTM2883HY-5S#PBF

Overview

The LTM2883HY-5S#PBF is a complete galvanic 6-channel digital μModule isolator manufactured by Analog Devices Inc. It integrates SPI, digital, or I²C interface capabilities with adjustable ±12.5V and 5V regulated power supplies within a single package. The device utilizes magnetic coupling for isolation, supporting data rates up to 20 Mb/s with an insulation voltage of 2500 Vrms. It operates on a single 3.3V or 5V supply and features bidirectional or unidirectional channel polarity. The component is housed in a BGA-32 package and is designed for high-density applications requiring robust signal and power isolation without external components.

Feature Summary

• Integrates six isolated digital channels with built-in power regulation
• Supports multiple interface protocols including SPI, digital logic, and I²C
• Provides adjustable isolated power rails for both sides of the barrier
• Eliminates need for external discrete isolation components

Applications

• Industrial automation systems requiring multi-channel isolation
• Medical equipment with strict galvanic separation requirements
• Test and measurement instrumentation interfaces
• Data acquisition systems with mixed-signal isolation needs

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm lot traceability and RoHS compliance status prior to integration. Check for moisture sensitivity level (MSL) handling requirements during storage and reflow soldering processes. Ensure ESD protection measures are implemented during assembly to prevent damage to the sensitive internal isolation barriers.

Selection Notes

Select this component when a compact solution for six isolated channels is required alongside integrated power generation. Consider the BGA-32 footprint constraints and thermal management needs for the specific PCB layout. Evaluate whether the adjustable power output meets the downstream circuit requirements compared to fixed-voltage alternatives. Verify compatibility with the target communication protocol speeds and voltage levels.

Part Context

This part belongs to the LTM2883 series of μModule isolators from Analog Devices. These devices represent a class of highly integrated solutions that combine signal isolation and power conversion in a single package. The series is designed to simplify design-in processes by reducing component count and board space while maintaining high reliability standards for industrial and medical applications.

Replacement Considerations

Direct substitutes include other LTM2883 variants such as LTM2883CY-5S#PBF or LTM2883HY-3S#PBF, depending on specific voltage and temperature range requirements. Verify pinout compatibility and electrical specifications before substitution.
