Trusted safety and data integrity
ADI’s Digital Isolation Solutions
Isolated Data
ADI’s iCoupler digital isolators enable robust solutions with the flexibility of up to six channels. Products meet stringent safety standards including the ability to isolate IS-IS with our intrinsically safe certified digital isolators. AEC Q100 automotive certified versions are also available.
- Standard Digital Isolators
Isolated Power Conversion
isoPower chip-scale transformers remove design complexity and optimize power solutions. μModule devices create solutions that provide additional auxiliary isolated power. Isolated amplifiers provide power supply engineers with an upgrade in speed, temperature, and transient response over traditional optocoupler options.
