1 Pcs Isolated USB chip ADUM4160BRIZ-RL Full-Speed/Low-Speed USB Digital Isolator SOIC-16-300mil

Description

Product Overview

The ADUM4160BRIZ RL is a high‑performance isolated USB digital isolator designed to meet the demanding requirements of modern industrial and scientific equipment. Housed in a 16‑lead SOIC package with a 300 mil (7.62 mm) pitch, the device offers a compact footprint while delivering full‑speed (12 Mbps) and low‑speed (1.5 Mbps) data isolation. Its architecture incorporates dual-channel isolation, providing bidirectional protection for both D+ and D‑ signals. The isolator features a robust silicon‑on‑insulator (SOI) technology that ensures high isolation voltage, typically 5 kV, while maintaining low propagation delay and minimal signal distortion. This combination of speed, isolation strength, and small form factor makes the ADUM4160RL an ideal choice for applications ranging from USB peripheral controllers to safety‑critical monitoring systems. The part is fully compliant with USB 2.0 specifications and has been qualified for operation across a wide temperature range, from –40 °C to +85 °C, guaranteeing reliable performance in harsh environments.

Usage

In industrial automation, the ADUM4160RL is frequently employed to protect communication links between programmable logic controllers (PLCs) and USB‑based sensors or actuators. By isolating the USB data lines, the device prevents ground loops and voltage transients from propagating into sensitive control circuitry, thereby extending system lifespan and reducing downtime. In medical instrumentation, the isolator safeguards patient‑connected devices from electrical hazards, ensuring compliance with stringent safety standards. It also finds use in test and measurement equipment where high‑precision data acquisition must be shielded from noisy power environments. Embedded developers integrate the chip into custom board designs for USB‑to‑UART bridges, data loggers, and portable diagnostic tools, taking advantage of its low power consumption and small package to meet size and energy constraints. The isolator’s ability to operate at both full‑speed and low‑speed makes it versatile for a broad spectrum of USB peripherals, from high‑bandwidth storage devices to simple human‑interface components.

FAQ

What isolation voltage does the ADUM4160RL provide?

The device offers a typical isolation rating of 5 kV, which is sufficient to protect USB data lines from high‑voltage spikes and ground‑loop currents in most industrial settings.

Can the isolator be used for both full‑speed and low‑speed USB devices?

Yes, the ADUM4160RL is designed to handle both full‑speed (12 Mbps) and low‑speed (1.5 Mbps) USB protocols, making it suitable for a wide range of peripheral types.

What is the recommended layout for optimal performance?

We recommend placing the isolator close to the USB connector, using short trace lengths for the D+ and D‑ lines, and providing proper ground clearance around the isolation barrier to minimize parasitic capacitance.
