LTM2883IY-3I#PBF

Overview

The LTM2883IY-3I#PBF is a complete galvanic 6-channel digital µModule isolator from Analog Devices. It integrates isolated SPI, I2C, and general-purpose digital channels with adjustable 12.5V and 5V regulated power supplies on the isolated side. The device operates with a single 3.3V or 5V supply on the primary side. Key electrical parameters include a data rate of up to 20 Mb/s, an isolation voltage of 2500 Vrms, and a common-mode transient immunity of 30 kV/µs. It features bidirectional and unidirectional channel polarities within a 32-pin BGA package.

Feature Summary

• Integrates six isolated digital channels with dual adjustable regulated power supplies for the isolated side
• Provides high common-mode transient immunity for reliable signal transmission in noisy environments
• Eliminates the need for external components by combining isolation and power management in a single module

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Automotive electronics interfaces demanding robust noise immunity

Procurement Notes

Verify the specific suffix and package type against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm availability status as distribution may vary. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the integrated power regulation meets the target circuit's load specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution is needed for multiple isolated digital signals combined with isolated power generation. It is suitable for designs requiring high-speed data rates and significant common-mode noise rejection. Consider the thermal performance and PCB layout constraints associated with the BGA package during the integration phase.

Part Context

This part belongs to the LTM2883 series of µModule isolators designed by Analog Devices. These modules consolidate complex isolation functions into small footprints, reducing board space and design complexity compared to discrete solutions. The series supports various communication protocols and power configurations for diverse industrial applications.

Replacement Considerations

Check for direct pin-compatible alternatives within the same LTM2883 family or other Analog Devices µModule isolators. Verify that any substitute maintains the required isolation voltage, channel count, and integrated power output capabilities.
