The LTM2883 is a complete galvanic 6-channel digital μModule^® (micromodule) isolator. No external components are required. A single 3.3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.

Available options are compliant with SPI and I²C (master mode only) specifications.

The isolated side includes ±12.5V and 5V nominal power supplies, each capable of providing more than 20mA of load current. Each supply may be adjusted from its nominal value using a single external resistor.

Coupled inductors and an isolation power transformer provide 2500V_RMS of isolation between the input and output logic interface. This device is ideal for systems where the ground loop is broken, allowing for a large common mode voltage range. Communication is uninterrupted for common mode transients greater than 30kV/μs.

Applications

Isolated SPI or I²C Interfaces
Industrial Systems
Test and Measurement Equipment
Breaking Ground Loops
