Product Overview

DC1079A-B is an demonstration board populated with the LTC4310-2 I2C isolator. The LTC4310 provides bidirectional I2C communication between two I2C buses whose grounds are isolated from one another. Each isolator encodes I2C bus logic states into signals that are transmitted across an isolation barrier to another isolator. The receiving isolator decodes the transmission and drives its I2C bus to the appropriate logic state. The isolation barrier can be bridged by an inexpensive Ethernet (or other) transformer to achieve communications across voltage differences reaching thousands of volts, or it can be bridged by capacitors for lower voltage isolation. DC1079A shows both transformer and capacitor techniques. Separate supplies are connected on opposite sides of the isolation barrier. Board is intended for use in I2C bus speeds from 100KHz to 400KHz.
