Technical Specifications

Using Analog Devices’ proprietary iCoupler® magnetic coupling and IsoPower® technology, this isolator features two unidirectional channels (1 input per side) in a 20-SOIC surface-mount package. The device provides reinforced isolation for signal and power domains, supporting half-duplex communication. Its high noise immunity and low-emission design make it ideal for EMI-sensitive applications. Surface-mount assembly (20-SOIC, 7.50mm width) ensures space-efficient PCB integration.

Typical Applications

• Industrial automation and PLC systems
• Motor control interfaces
• HVAC and building management networks
• Medical equipment data acquisition
• Renewable energy inverters

About Digital Isolators

Digital isolators provide critical galvanic separation between circuit sections, preventing dangerous voltage transients and ground loops from damaging sensitive electronics. Unlike optocouplers, magnetic-based isolators offer higher speed, lower power consumption, and superior noise immunity.

In industrial and automotive systems, these components ensure safe data transfer across isolation barriers while meeting stringent safety standards like UL, CSA, and VDE. Their integration reduces component count, saves board space, and enhances system reliability in power-harsh environments.

Packaging Options

Available in factory-sealed tubes for automated assembly processes. Contact PCX for reel packaging alternatives and volume pricing.

Frequently Asked Questions

Q: Does this isolator require external components for power isolation?
A: No – the integrated IsoPower® DC/DC converter provides isolated power without external circuitry.

Q: What certifications does the ADM2587EBRWZ hold?
A: It complies with UL 1577, CSA, and VDE V 0884-10 safety standards.

Q: Can I use this for full-duplex RS485 communication?
A: No, its half-duplex design supports one transmitter/receiver pair. Use ADI’s ADM2687E for full-duplex.

Q: Is termination required for short cable runs?
A: For runs under 10 meters, termination may not be necessary. Consult the datasheet for specific guidelines.

Q: How does magnetic isolation differ from optical isolation?
A: Magnetic coupling offers higher data rates, lower latency, and better aging performance than LED-based optocouplers.

Q: Can it withstand industrial voltage surges?
A: Yes, its 25kV/µs common-mode rejection provides robust protection against electrical noise and surges.
