ADuM3160 USB To USB Isolator Audio Signal Power Supply Isolation,USB2.0,1500V

Features:

This product is suitable for the following users:

1. Work environment with strong electricity and strong interference

Some circuits contain strong electricity, strong interference (such as high voltage, inverter, motor drive, etc.) environment,

When it comes to connecting with a computer, it must be isolated to ensure the computer and personal safety.

2. Noise sensitive area

Everyone knows that computers are a big source of noise. In the noise sensitive field, we can isolate the USB interface through this device.

Such as high-precision USB data acquisition system, HIFI sound system.

3. USB debugging device

For example, various USB interface JTAG/SWD emulators, ISP/ASP/IAP/ICP downloaders, etc.

When you are unable to connect during the debugging process and the simulation is abnormal, you can use the USB isolator to try to improve.

4. Various industrial control USB devices

In industrial environments, USB devices often crash, such as USB mouse, keyboard, USB to serial port and other communication devices.

USB isolators reduce the chance of crashes and damage to these devices in industrial environments.

Sometimes it is necessary to extend the USB cable, the USB isolator can act as a very good USB repeater,

and can also isolate the ground pressure difference between upstream and downstream devices.

5. Other common USB peripherals, such as mouse, keyboard, USB sound card, USB flash drive, printer, digital camera, USB hub (HUB), USB camera.

Analog Devices’ features their ADuM3160 isolators with iCoupler® technology for general multichannel isolation
The ADuM3160 is a USB port isolator based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics and is easily integrated with low and full speed USB-compatible peripheral devices.

Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required. Because the USB lines must switch between actively driving D+/D− and allowing external resistors to set the state of the bus, the ADuM3160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.

The ADuM3160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream-facing port isolator. Isolating the upstream port provides several advantages in simplicity, power management, and robust operation.

The isolator has a propagation delay comparable to that of a standard hub and cable. It operates with the bus voltage on either side ranging from 4.5 V to 5.5 V, allowing connection directly to VBUSx by internally regulating the voltage to the signaling level.

The ADuM3160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device draws low enough idle current that a suspend state is not required. A 5 kV, reinforced insulation version, the ADuM4160, is available.
