LTM2886HY-3S#PBF

Overview

The LTM2886HY-3S#PBF is a complete current digital µModule isolator manufactured by Analog Devices Inc. It integrates an SPI interface with magnetic coupling isolation technology, eliminating the need for external components. The device operates from a single 3.3V or 5V supply and utilizes an integrated isolated DC/DC converter to power both sides of the interface. Key electrical parameters include a data rate of 4MHz and 8MHz, a reverse channel count of 3, a maximum fall time of 35 ns, and a common-mode transient immunity (CMTI) of 30kV/µs. It features a bidirectional and unidirectional polarity configuration within a 32-pin BBGA package.

Feature Summary

• Integrates an isolated DC/DC converter to power both sides of the interface without external components
• Utilizes magnetic coupling technology to transmit signals across the isolation barrier
• Provides high common-mode transient immunity for reliable signal transmission

Applications

• SPI bus module isolation in industrial systems
• Digital isolation for embedded designs requiring stable timing sources
• Interface isolation in communication systems
