• ADUM3160 communication issue

    I constantly get "USB device not recognized". The device works fine (direct connection with usb cable). I measured 5V on VDD1 and the isolated 5V on VDD2.

    Schematic is like above, PDEN (pin 4) is connected to VDD1 and PIN (pin 12) is connected…

  • ADUM3160 communication failed issue

    Hi ADIexpert

    I use ADUM3160 to isolate USB data from my CPU to external USB device (in my test, it's a keyboard)

    please see my  test circuit and configuration below

    ---------------------

    upstream

    VBUS1: 5V

    VDD1/PDEN/SPU: 3.3V

  • RE: ADUM3160 ST-link

    Hi,

    Apologies for the delay in responding. Can you please mention what specific IC is connected to ADuM3160, cropped off on the right of the schematic? I note there's a 24 MHz crystal connected which is usually required for USB 2.0 high speed mode (480…

  • ADUM3160 isolation for controller's VBUS sensor pin

    Hi,

    I want to use ADUM3160 for my controller's USB which is self powered and running in device mode.

    VBUS pin is used for connect / disconnect sensing. but I do not see provision for the VBUS isolation. Can one guide me how to achieve the isolation…

  • ADUM3160 problems

    All,

    I have a ADUM3160 between a USB-B connector and a Microchip PIC32MX270 processor. This is a USB UAC stereo Audio DAC capable of 24/96 and operating in the asynchronous configuration.

    In the async protocol a feedback pipe is established to make sure…

  • [硬件设计/求助]ADUM3160在超过40摄氏度时失效

    ADUM3160在超过40摄氏度时失效

    我确信芯片没有问题,因为芯片是从ICKEY正规渠道购买的,其他元件耐温也没问题.

    ADUM3160两侧VBUS由隔离电源供电,压差大致20mV,前后级包含ESD.

    做了两个电路,第一个电路能正常工作于40度以下,但这可能是个错的电路.

    第二个电路和手册设计相符,但是会提示未识别设备(不管插入什么设备都是,USB1.0/USB1.1都是)

    第二个电路的PCB图如此布局.

    只要不超过40度,工作完全正常,超过40度后,冷却到常温,需要重新插拔才能工作正常

  • Placement of ADUM3160 and ADUM5020, is it possible to place them on opposing sides of the pcb

    Hello,

    I am in the need for a USB Isolator with minimal footprint and I was wondering if it is possible to place the ADUM5020 on the top side and the ADUM3140 on the bottom side? SO that they are right above each other. The will be an isolation cut, so…

  • ADuM3160 - Problems during EMC tests

    Hello,

    we currently use an ADuM3160 to isolate our USB port which is running as USB host. During EMC testing with a bulk current injection (BCI) probe,

    the USB connection is interrupted when testing between 30~32 MHz.

    Is the ADuM3160 internally working…

  • ADuM3160 for USB isolation

    I want to use the ADUM3160 to isolate a USB Line. The ADUM3160 must be
    connected direclty to a PC USB output, and have to drive a USB cable and the
    USB peripheral. What I want to know is, can I use this part also in USB1.1
