• Question: RS485 connection between 5V and 3.3V

    Hi there I have a question about ADM2484.
    Are there any issues if I use ADM2484 like the attached file?
    (The master is ADM2484 with 3V operation and the slave is 5V operation such as ADM4581)

    I'm a bit worried about the current flow from ADM4851 to ADM2484…

  • RE: need help with ADM2484E

    Hello Yuri,

    Thank you for the additional oscilloscope plot. This does look like unexpected bus contention for a short interval. That is to say, one of the other nodes is attempting to transmit at the initial interval where the ADM2484E is enabled. This…

    Hi

    I have a question ADM2484E.

    ADM2484E DS is write,

    'The logic side of the device can be powered with either a 5 V or a 3.3 V supply, whereas the bus side requires an isolated 3.3 V supply.'

     

    And ,

    Vdd2 ABSOLUTE MAXIMUM RATINGS is 6V max…

  • RE: ADM2484E compliant with IEC 61010-1

    Hi newton,

    The ADM2484E is compliant to IEC 61010-1 3rd Ed.

    The ADM2484E data sheet needs to be updated.

    Please see this link to the CSA webpage:

  • ADM2484E voltage specification

    Q 

    the data sheet for the ADM2484E device lists the voltage supply range for VDD1
    from 3.3V to 5V. The VDD2 supply is rated 3.3V. On page 16, observing Table 7
    we can see VDD1 is rated to 7V max, however VDD2 is rated up to 6V.

    We were…
