LTM2883HY-3S#PBF

Overview

The LTM2883HY-3S#PBF is a µModule digital isolator from Analog Devices Inc. housed in a 32-ball BGA package. It integrates six independent isolation channels supporting SPI, digital, or I²C interfaces with bidirectional and unidirectional polarity options. The device operates on a supply voltage range of 3V to 3.6V and delivers a data rate of 20 Mb/s. Key electrical specifications include an isolation voltage of 2500 Vrms and a common-mode transient immunity (CMTI) of 30 kV/µs. The module incorporates adjustable 12.5V and 5V regulated power supplies for the isolated side.

Feature Summary

• Integrates six independent magnetic coupling isolation channels within a single compact module.
• Includes integrated adjustable regulated power supplies providing 12.5V and 5V outputs for the isolated domain.
• Supports flexible interface configurations including SPI, digital logic, and I²C protocols.
• Provides high common-mode transient immunity to ensure signal integrity in noisy environments.

Applications

• Industrial communication systems requiring robust signal isolation
• Medical equipment needing galvanic separation between circuits
• Automotive electronic control units demanding high reliability
• Test and measurement instrumentation interfaces

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm that the specific suffix matches the required thermal and electrical characteristics. Ensure compliance with RoHS directives and check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a high channel count and integrated power regulation are required in a small footprint. Compare against the LTM2892 series if higher isolation voltage ratings are necessary. Evaluate the BGA-32 package constraints against available PCB real estate and routing complexity.

Part Context

This part belongs to the LTM2883 µModule Isolator family designed for complex system isolation needs. It consolidates multiple discrete components into a single solution to reduce board space and design time. The HY-3S variant specifies the commercial temperature range and specific pinout configuration.

Replacement Considerations

The LTM2883CY-5S#PBF serves as a functional substitute within the same family, offering similar isolation capabilities but potentially differing in package type or specific regulatory features. Verify pin compatibility before substitution.
