• LTM2881 & LTM2882 EMI ISSUE

    Dear FAE,

    At present, designed two product:USB/RS232 and USB/RS422, selected ADI chips: LTM2881 & LTM2882,

    SCH and PCB design are basically based on the recommended design of LTM2881 & LTM2882,

    EMI prescan has been preliminarily carried out.…

  • LOADING LTM2882

    Hi,

    I am using LTM2882 in our design. In datasheet it is written that "Isolated DC Power: 5V at Up to 200mA", Can we load VCC2 pin with a 100mA constant load, while full RS232 communication is there?

  • LTM2882 communication issue

    Hi,

    I am using LTM2882-3 in my design and implemented half duplex serial communication.

    I am facing issue in  RS422 communication.

    I did loop back on uart signals of processor  isolating LTM2882 it  is happening.

    But when i use LTM2882 in the path no communication…

  • LTM2881 and LTM2882 in Space Applications

    Hi,

    We are considering using the LTM2881 and LTM2882 in a space application for RS-232 and RS-422 communications.

    Does this sound like a good idea?

    Do you have any radiation or vacuum concerns about this chip?

    Does it have any space heritage that you know…

  • Ground on LTM2882 and similar devices from Analog. 

    When you have these isolated transceivers, do you need to connect the isolation ground to the device you are getting isolation from? I would imagine the answer would be yes, but the datasheet says to connect it to the shield. Is it possible to not connect…

  • RE: LT1137A demo board

    Hi Patrick, 

    Unfortunately we do not have an evaluation board available for the LT11337A or our other multi-channel RS232 transceivers. 

    We do have evaluation boards available for our isolated RS232 devices, the ADM3251E/2E and LTM2882, our wide supply…

  • RE: ADM3251 isolated power supply

    Hi,

    1) If you already have a 3.3V isolated power supply available on side 2, then the part will use less power overall by powering Vcc = 3.3V (isolated DC-DC disabled). Otherwise, using the integrated isolated DC-DC would be preferred in order to save…
