Digital Isolator Product Selection
and Resource Guide
Performance • Integration • Efficiency • Reliability • Safety
Digital isolators with iCoupler® technology enable designers to implement
isolation in designs without the cost, size, power, performance, and reliability constraints found with optocouplers. iCoupler digital isolators also meet
the wide range of creepage/clearance requirements and are the industry’s
only digital isolators with certified 8 mm creepage. With more than half a
billion channels shipped into the field, these magnetically isolated products
meet the same rigid safety standards as optocouplers.
Advantages of the Broadest Portfolio of Digital Isolators
Performance
4× improvement in data rate and timing specifications.
Integration
Multiple isolation channels integrated with other functions reduce
size, cost, and design complexity.
Power Consumption
Operates at power levels up to 90% lower than optocouplers.
Portfolio Offerings
• Single and multichannel
data isolators
• I2C ® digital isolators
• Digital isolators with
isolated power: isoPower ®
• Isolated RS-485 transceivers
• USB isolators
• Isolated gate drivers
www.analog.com/icoupler
• Isolated CAN transceivers
• Isolated RS-232 transceivers
• Isolated Σ-∆ modulators
Ease of Use
Standard digital CMOS interfaces mean no external components
needed to connect to other digital devices.
Reliability
Eliminates LED wearout traditionally found in optocouplers.
Safety
Meets same rigid safety standards as optocouplers, including
reinforced insulation.
