LTM2883IY-3S#PBF

Overview

The LTM2883IY-3S#PBF is a complete galvanic 6-channel digital micromodule isolator manufactured by Analog Devices Inc. It integrates SPI, digital, or I2C isolation with adjustable 12.5V and 5V regulated power supplies within a single package. The device operates on a single 3.3V or 5V supply and features a 32-BBGA package. Key electrical parameters include a data rate of 4MHz to 8MHz, an insulation voltage of 2500Vrms, and a common-mode transient immunity (CMTI) of 30kV/µs. Propagation delay is specified at 60ns, with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates six isolated channels with built-in adjustable regulated power supplies for both sides of the isolation barrier.
• Provides high common-mode transient immunity to ensure signal integrity in noisy environments.
• Eliminates the need for external components by combining isolation and power management in a single module.

Applications

• Industrial automation systems requiring robust galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Data acquisition modules interfacing with isolated sensors

Procurement Notes

Verify the specific suffix '3S' against official Analog Devices documentation to confirm pinout and internal regulator configurations. Ensure compatibility with the target PCB footprint for the 32-BBGA package. Check for moisture sensitivity level requirements during storage and handling. Confirm that the integrated power regulation meets the load requirements of the isolated side circuitry before finalizing procurement.

Selection Notes

Select this component when a compact solution is needed for multi-channel isolation with integrated power generation. It is suitable for applications demanding high CMTI and low propagation delay. Compare against standard discrete isolators to evaluate space savings and reduced bill of materials. Ensure the input logic levels match the source interface protocols such as SPI or I2C.

Part Context

This part belongs to the LTM2883 series of digital micromodule isolators. These modules are designed to simplify system design by integrating isolation technology with power conversion capabilities. The series supports various communication protocols and offers different channel counts and power options within the same family architecture.

Replacement Considerations

Check Analog Devices datasheets for direct pin-to-pin replacements within the LTM2883 series. Verify if alternative suffixes offer different power ratings or channel configurations. Cross-reference with other ADI isolator families only if form factor constraints allow redesign.
