ADUM320N0BRIZ-RL

Overview

The ADUM320N0BRIZ-RL is a robust dual-channel digital isolator from Analog Devices, utilizing proprietary iCoupler magnetic coupling technology. It provides electrical isolation between two circuits with a single channel of data flow in each direction (2:0 configuration). The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical specifications include an insulation voltage of 5000 Vrms, a typical propagation delay of 7.2 ns, and a maximum pulse width distortion of 500 ps. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in a standard SOIC-16 package.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-reliability signal transmission without optical components.
• Provides galvanic isolation with a rated insulation voltage of 5000 Vrms for safety-critical applications.
• Supports bidirectional data communication with independent channels for input and output paths.
• Maintains signal integrity with low propagation delay and minimal pulse width distortion.

Applications

• Industrial automation systems requiring isolated sensor interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise environments
• Communication gateways isolating logic levels from power stages

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for specific humidity sensitivity handling requirements during storage and assembly processes. Ensure design compatibility with the specified SOIC-16 footprint and pinout arrangement.

Selection Notes

Select this component when dual-channel bidirectional isolation is required within a compact form factor. Consider the 150 Mb/s data rate limit for high-speed interface needs. Evaluate the 5000 Vrms insulation rating against system safety standards. Compare power consumption characteristics if battery-operated or thermally constrained designs are involved.

Part Context

This device belongs to the ADUM320N series of digital isolators designed for robust performance in noisy environments. It represents Analog Devices' implementation of silicon-based isolation technology, offering advantages over traditional optocouplers such as longer lifespan and better thermal stability. The series is engineered for industrial and commercial applications demanding reliable signal transfer across isolation barriers.

Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure any replacement maintains equivalent insulation voltage, data rate, and package dimensions. Verify that alternative devices support the same unidirectional channel configuration and operating temperature range.
