Digital Isolators

Category Introduction

Digital Isolators electrically separate circuits but still allow for digital signals to be transferred between them. The technology types are capacitive coupling, giant magnetoresistive (GMR), or magnetic coupling. The number of channels range from 1 to 10 and the channel types can be bidirectional, unidirectional, or both.
