Overview
The LTM2883IY-5S#PBF is a complete digital µModule isolator from Analog Devices Inc., designed for SPI, digital, or I²C interfaces. It integrates a magnetic coupling isolation barrier with adjustable 12.5V and 5V regulated power supplies. The device features six channels, supports bidirectional and unidirectional data flow, and operates at data rates up to 20 Mb/s. It provides an insulation voltage of 2500 Vrms and utilizes a 32-ball BGA package (15x11.25 mm). Powered by a single 3.3V or 5V supply, it eliminates the need for external components.
Feature Summary
- Integrates isolated DC/DC converter for dual-side power without external components
- Supports SPI, digital, and I²C interface protocols
- Provides high common-mode transient immunity via magnetic coupling technology
Applications
- Industrial communication systems requiring galvanic isolation
- Medical equipment signal interfacing
- GPS system data transmission lines
Procurement Notes
Verify component authenticity through authorized Analog Devices distributors. Confirm the specific suffix 'IY-5S' matches required temperature range and packaging specifications. Check current availability status as supply may be limited. Ensure ESD handling procedures are followed during installation due to the sensitive BGA package type.
Selection Notes
Select this module when integrating SPI, digital, or I²C signals across isolation barriers. It is suitable for designs requiring integrated power regulation on both sides of the isolation gap. Consider the 32-BGA footprint for PCB layout constraints. Verify that the 2500 Vrms isolation rating meets the safety requirements of the target application environment.
Part Context
This component belongs to the LTM2883 series of µModule isolators. It shares functional similarities with other devices in the family but is distinct in its specific channel count and interface support. The part number indicates the industrial temperature grade and specific pin configuration within the broader product line.
Replacement Considerations
Direct substitutes include LTM2883CY-5S#PBF for commercial temperature variants. Evaluate LTM2892IY-I#PBF if higher 3500 Vrms isolation is required. Ensure pin compatibility and thermal performance match the original design constraints before substitution.
FAQ
Does the LTM2883IY-5S#PBF require external components for operation?
No, it is a complete µModule isolator that integrates all necessary components, including the isolated DC/DC converter.
What is the maximum data rate supported by this module?
The module supports data rates up to 20 Mb/s for SPI, digital, and I²C interfaces.
