ADUM1286ARZ-RL7

Overview

The ADUM1286ARZ-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler technology for magnetic signal transmission. It provides galvanic isolation with an insulation voltage of 3000 Vrms and supports data rates up to 1 Mb/s. The device operates within a supply voltage range of 3.135 V to 5.5 V, consuming typical currents of 2.1 mA and 2.3 mA per channel. Key electrical parameters include a propagation delay of 23 ns and rise/fall times of approximately 3 ns. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an SOIC-8 package.

Feature Summary

• Integrates two independent channels for bidirectional or unidirectional signal isolation using on-chip transformer technology.
• Provides high common-mode transient immunity and robust noise rejection without requiring external components.
• Supports default low output configuration to ensure safe states during power-up or fault conditions.

Applications

• Industrial process control systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics gate drive circuits for inverters and converters

Procurement Notes

Verify the specific suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with standard SOIC-8 footprint requirements during PCB layout. Confirm that the requested quantity aligns with available distribution channels, as supply status may vary. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when dual-channel isolation is required within a compact SOIC-8 footprint. It is suitable for applications demanding high common-mode transient immunity and low power consumption. Consider the 1 Mb/s data rate limit and 3000 Vrms isolation rating against system requirements. Evaluate thermal performance within the specified operating temperature range to ensure reliable long-term operation in harsh environments.
