Inside iCoupler® Technology:
Differential Data Transfer: What's the Difference?
The primary function of an isolator is to pass some form of information across an electrical barrier while preventing current flow. Isolators are constructed from an insulating material that blocks the current flow, with a coupling element on both sides of the barrier. Information is typically encoded before being transmitted across the barrier by the coupling elements.
iCoupler digital isolators from Analog Devices use chip-scale microtransformers as the coupling element to transfer data across a high quality polyimide insulation barrier. Two primary methods of data transfer have been used in iCoupler isolators: single-ended and differential. Selection of a data transfer scheme involves engineering trade-offs to optimize the desired characteristics of the end product.
