• Question about ADM3065E

    Hi All,

    The input signal to A and B pins at start up goes down to about -20V but ADM3065E seems to clamp it to about -11V as attachment.

    1) Does ADM3065E has any clamp function inside?

    2) If 1) is yes, the value of the negative clamping voltage is lower…

  • ADM3065E Receiver Pin Spec.

    Dear All:

    ADM3065E is 3.0V to 5V working voltage IC ,but receiver Logic output pin not define this max voltage , If IC working voltage is 3.3V is pin max voltage is 3.3V either meet  standard EIA-485 Spec. 5V?? have any information to me refer. ??

    Hello Yuji,

    Thanks for showing your interest in one of our RS-485 Transceivers. The maximum data rate that can be achieved with ADM3065E is 50 Mbps, but it also depends on the other working conditions like the temperature and supply voltage.  If you're…

  • RE: Question about RS-485 Tranceiver

    Hi Richard,

    Thank you for supporting this case.

    For logic voltage=3.3V case, I can use ADM3065E. For logic voltage=5V case, I can use the new ADM3065E.

    I have another question. Some products have the following feature.

    "Interoperable with 5V logic…

  • RE: ADM3061E RO issue

    Thank you for providing more detail on your setup.

    The 1nF capacitor has the affect of slowing down the rise/fall edges into the optimum region for the ADM3061E, giving correct operation. The ADM3061E is optimized for slew rate limited drivers for operation…

    Hi slavas,

    We are in the process of updating the ADM3065E/ADM3066E data sheet. The branding will be added on the next revision. I apologize for any inconvenience.



  • 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: Solution to Open Fale-Safe (AN-960)

    Fail safe biasing is only required at one location on the RS-485 bus.

    Many ADI RS-485 transceivers include an integrated RS-485 failsafe circuit, eliminating the need for external fail safe biasing resistors.

    For example, the ADM3065E includes open…
