ADUM4160BRIZ

Overview

The ADUM4160BRIZ is a digital isolator from Analog Devices, designed for USB peripheral isolation. It features three channels with bidirectional communication capabilities. The device supports low-speed (1.5 Mbps) and full-speed (12 Mbps) data rates, ensuring compatibility with USB 2.0 standards. It operates within a supply voltage range of 3.1 V to 5.5 V and provides an insulation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 70 ns, maximum rise/fall times of 300 ns, and a typical operating supply current of 6 mA. The component is housed in a 16-pin SOIC package and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates iCoupler technology combining high-speed CMOS processes with monolithic air core transformer technology for robust signal transmission.
• Provides short-circuit protection for differential data lines to enhance system reliability during fault conditions.
• Supports bidirectional communication, allowing flexible data flow between isolated domains without direction control overhead.

Applications

• Isolation of USB peripherals in industrial equipment requiring safety compliance.
• Medical devices needing defibrillation proof connections and leakage current protection.
• PC peripheral interfaces replacing legacy RS-232 or parallel ports with isolated USB connections.

Procurement Notes

Verify the specific suffix 'BRIZ' against official Analog Devices documentation to confirm the exact package variant and tape/reel configuration. Ensure that the ordering information matches the required moisture sensitivity level and RoHS compliance status as defined in the latest datasheet revision. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing systems requiring galvanic isolation for USB 2.0 low and full-speed interfaces. It is suitable for applications demanding high common-mode transient immunity and compact form factors. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate the 5000 Vrms insulation rating against the specific safety standards applicable to the end product environment.
