LTM2893IY-1#PBF

Digital Isolators Overview

The LTM2893IY-1#PBF is a digital isolator module from Analog Devices, housed in a BGA-36 package. It supports bidirectional data transmission at speeds up to 100 Mb/s with a propagation delay of 80 ns. The device features magnetic coupling isolation rated at 6000 Vrms and offers a common-mode transient immunity of 50 kV/µs. Operating on a supply voltage between 3 V and 5.5 V, it draws 12 mA of quiescent current. It includes four forward and four reverse channels, supporting SPI protocols, and functions within a temperature range of -40°C to +85°C.

Digital Isolators Feature Summary

• Integrates high-speed magnetic coupling isolation for reliable signal transmission across galvanic boundaries.
• Supports bidirectional data flow with dedicated forward and reverse channel configurations.
• Includes shutdown functionality to minimize power consumption during idle states.
• Designed for compact surface-mount integration via a dense ball grid array footprint.

Digital Isolators Applications

Digital Isolators Procurement Notes

Verify the specific suffix '-1' against official Analog Devices documentation to confirm pinout and functional variations compared to standard variants. Ensure compatibility with your system's voltage levels and protocol requirements before procurement. Check for moisture sensitivity handling instructions due to the BGA packaging type. Confirm availability through authorized distributors as supply status may vary by region.

Digital Isolators Selection Notes

Select this component when high-speed serial communication requires robust galvanic isolation exceeding standard optocoupler capabilities. Consider the BGA-36 package constraints for PCB layout and thermal management. Evaluate the 6000 Vrms insulation rating against your system's safety standards. Ensure the 100 Mbps data rate aligns with your application's bandwidth needs without introducing excessive latency.

Digital Isolators Part Context
