• power supply of ADM3078E

    Hi

    can ADM3078E be powered using 5V?

    thanks

  • ADUM3402 and ADM3078 versus ADM2682

    I have an existing RS485 half duplex design using the ADUM3402, the ADM3078 running at 3.3V and a DC-DC convertor. I'm looking to save some space (as always) and am considering using the ADM2682. However, I've been trying to interpret the supply current…

  • [ADM3078E]recommended mode when hot-swap happen

    Hello,

    The customer would like to get advice about hot-swap ADM3078E.

    ADM3078E has thee mode (shut-down, rx, tx).

    Do you have any particular recommended mode when ADM3078E face hot-swap?

    Thank you for your help as always.

    Best regards,

    Sofy

  • ADM3078E pcb layout question regarding trace impedance

    Hello,

            I am currently working on a design that includes a RS485 network.  Currently there is a PC with PCI based RS485 transceiver card and I am designing a circuit that will be reporting data to that PC.  The RS485 node that I am designing will never…

  • The input amplitude dependency of ADM3078E propagation delay

    Hi

    RS485 receiver should operate by +/- 200mV differential signal.

    ADM3078E receiver spec defined the delay time by +/- 1V input.

    Could you show us the propagation delay at +/- 200mV input?

    How about input amplitude dependency?

    Regards

  • RE: Please ask what causes adm485 to fail to communicate?

    Hi Clark,

    The ADM485E is specified for a Vcc supply of 4.5-5.5V.  Is there any reason why your design cannot meet this specified range?

    We have a wide range of half duplex RS-485 transceivers that can operate at 3.3V supply ranges, For example the ADM3065E…

  • RE: ESD protection for AMD4850ARMZ

    Hi Akhil,

    Just an extra note -- ADI also has a range of more ESD robust RS-485 transceivers at 3V and 5V operation:

    5 V operation:

    ADM485E, ADM487E, ADM1487E have 15 kV HBM ESD protection

    3 V operation:

    ADM3070E - ADM3078E have 15 kV HBM ESD pro…

  • RE: RS485 network biasing question

    Excellent point!

    If you have a 4V VOD on a 5V transceiver, for example, & there's an external resistor biasing network on the other side to 3.3V, this could present a current path into the supply.  This path would need to be blocked alright.  But…
