ADUM4160 USB Isolator Module | Signal & Power Isolation (USB 2.0 Full Speed)
Safeguard your computer's valuable USB ports and eliminate frustrating ground loop noise with this ADUM4160 USB Isolator Module from Abhir-online. Based on Analog Devices' advanced iCoupler® technology, this module provides robust galvanic isolation for USB connections, crucial for industrial environments, sensitive audio setups, and protecting host devices.
It offers full electrical isolation for both the USB data lines (2500V via ADUM4160) and the USB power line (1500V via isolated DC-DC converter). This breaks ground loops, which are a common source of noise in USB audio systems, and protects your PC or host device from voltage surges or faults from connected USB peripherals.
Compatible with USB 2.0 Low Speed (1.5 Mbps) and Full Speed (12 Mbps) devices, it requires no external drivers for operation (plug-and-play). The onboard isolated power supply provides up to 1W (~150-200mA @ 5V), sufficient for most low-power devices like mice, keyboards, or USB-to-serial adapters. For devices requiring more power, an external 5V supply can be connected via the Micro USB port. Comes complete with a protective acrylic case and necessary USB cable from Abhir-online.
Features and Highlights:
- Utilizes Analog Devices ADUM4160 chip with iCoupler® technology.
- Provides USB Signal Isolation (2500V) and Power Isolation (1500V).
- Compatible with USB 2.0 specification (Low Speed 1.5Mbps & Full Speed 12Mbps).
- Important: Does NOT support High Speed (480Mbps) or USB 3.0 devices.
- Eliminates ground loop noise, ideal for USB Audio devices (DACs, Interfaces).
- Protects host computer USB ports from electrical surges and faults.
- Driverless operation (Plug-and-Play).
- Onboard isolated power supply (0.75W-1W, approx. 150mA max current).
- External 5V power input (Micro USB) for higher-power USB devices (>150mA).
- Includes protective transparent acrylic case and USB A-to-B cable.
- Wide operating temperature range (-40°C to 85°C).
Benefits and Advantages:
- Enhances system safety by isolating host computer from USB peripherals.
- Breaks ground loops, significantly reducing noise in audio and measurement applications.
- Protects expensive host equipment (PCs, laptops) from potential damage.
- Improves signal integrity in noisy electrical environments.
- Plug-and-play simplicity, no drivers needed for basic operation.
- Compact module with protective case, ready to use, from Abhir.
Applicable Applications and Practical Usage Scenarios:
- Connecting USB Audio DACs or interfaces to eliminate computer noise and hum.
- Industrial control systems requiring isolated USB communication.
- Connecting USB debugging tools (programmers, debuggers) safely.
- Protecting host computers when connecting potentially faulty or unknown USB devices.
- Medical equipment requiring electrical isolation for USB ports.
- Any scenario needing ground loop breaking or robust USB port protection at Low/Full speed.
Compatibility:
Essential for audiophiles, industrial engineers, electronics developers, technicians, and anyone in Saudi Arabia/GCC needing safe, isolated, and noise-free USB connections for sensitive equipment.

Special instructions and safety precautions:
- Verify your USB device operates at Low Speed (1.5Mbps) or Full Speed (12Mbps). This isolator WILL NOT WORK with High Speed (480Mbps) or USB 3.0 devices. Most devices are backward compatible, but verify if unsure.
- If the connected USB device draws more than ~150mA, connect a stable external 5V power supply to the Micro USB input port. Failure to do so may result in unstable operation for the device.
- Use the included USB A-Male to B-Male cable (or a similar quality cable) to connect the isolator's input (USB-B) to the host computer.
- Connect your USB device to the isolator's output (USB-A).
- Ensure all connections are secure.
