The LTM2810 is a complete galvanic digital µModule® (micromodule) isolator. No external components are required. Individual 3V to 5.5V supplies power each side of the digital isolator. Separate logic supply pins allow easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.
Module options are available with compatibility to SPI (LTM2810-S) and I2C (LTM2810-I), master mode only, specifications.
The module includes an integrated transformer driver on the logic side and an LDO on the isolated side to regulate the rectified transformer output. The LDO output is nominally 5V but may be overdriven.
Coupled inductors provide 7500VRMS of isolation between the input and output logic interface. This device is ideal for systems with different ground potentials, allowing uninterrupted communication through large common mode transients faster than 50kV/μs.

Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
Demonstration circuit 2832A is a serial peripheral interface bus (SPI) or inter-IC bus (I2C) µModule isolator with integrated transformer driver featuring the LTM2810. Isolated power is generated by the integrated transformer driver and transformer included on the demo board. It communicates all necessary signaling across the isolation barrier through Analog Devices isolator µModule technology.
