  • ADM3075E的接收器输出电流疑问??

    ADM3075E的手册上有个图,如果把接收器的输出引脚与MCU的对应引脚直接相连,则上图的接收器输出电流变化图是指的MCU的引脚容忍的输入电流要能达到23mA?

  • RE: EVAL-CN0359-EB1Z polling over RS485 not working

    Hi osullivan,

    Do you have an oscilloscope you can use to probe the RO and DI signals of the ADM3075E (Pins 1 and 4 of U7)?

    The two reasons that I see are that the ADM3075E is not working or the software was not loaded correctly. If the RO pin signals…

  • RE: CN0359 rs485 Problem Need A Help

    Hi raseyns,

    I think you have already done a lot of debugging for this issue but I need some more info to understand your setup. You said that you added the adum7641 between the mcu and the ADM3075. Can you show me a general connection diagram for this…

  • RS485使能端控制?

    想问一下,使用ADM3075E的时候,RE的使能端可以外接个上拉电阻,DE端可以外接个下拉电阻吗?阻值取多大?

  • ADM3075EARZ: What's its impedance when no supply is applied?

    We are designing a new system with a bus RS485, using ADM3075EARZ as driver. In
    this system, not all the RS485 drivers are powered at all times, because they
    don't have the same power supply. What happens with the bus impedance when one …
