About Digital Isolators

Digital isolators provide critical galvanic separation between circuit sections while transmitting data signals across voltage domains. Unlike optocouplers, they use CMOS technology for higher speed, tighter timing accuracy, and longer lifespan without LED degradation.

These components are essential for safety compliance (UL/ISO standards), noise immunity in industrial environments, and preventing ground loops in multi-voltage systems. Modern isolators like the ADUM series enable compact designs with superior EMI performance compared to legacy solutions.

Packaging Options
