• LTC4331 PoDL

    HI All,

    can you tell is it possible to couple DC power to the LTC4331 twisted pair in order to supply the I2C slave ?

    Best Regards,


  • Most rugged I2C bus range extender (LTC4331 not in stock today)


    Q1) Is there a good in-stock chip solution to be used as a I2C bus extender?

    We have a product with 2m long I2C communication between a master unit and slave peripheral unit that has some bit errors. Management would like to avoid not using I2C…

    Hi Kazu,

      you can use either resistor value.


  • CTRL pin on LTC4331


    The CTRL pin is described as controlling the remote from the local. What does the local control?

    I'm using the local and the remote CTRL pins open. Is there any problem?



  • LTC4331: repetitive slave side faults

    Hello there,

    We are using the LTC4331 in our equipment, but randomly, our master receives NACK signals after sending a slave address. These slave addresses has been correctly acknowledged over few previous transactions, and the problem is manufacturer…

  • Question about Link Rate of LTC4331


    Is the I2C link rate limited by the SCL frequency?

    I am thinking of setting the link rate to 500kHz or 1MHz with the SCL frequency = 400kHz.

    Which link rate (500kHz or 1MHz) is better?



  • LTC4331, remote I2C interface doesn't respond


    I'm experimenting with the LTC4331 demo board, with my own uproc board. My setup is:

    uproc <===> local LTC4331 <===> cable <===> remote LTC4331 <===> EEPROM

    program is simple: continuously reading from (remote) EEPROM,…

  • Unexpected behavior of LTC4331

    Hi AD-support,

    we have an issue with the LTC4331 device.

    During our debugging we implemented a test that reads a single byte over and over again from a device on the remote side of the LTC4331.

    During the test we gradually increase the time between two…

  • Multiple LTC4331 on the same line ?


    I've readed the datasheet of the LTC4331 and I'm in a case pretty similar to the one below:

    I need sa solution like the central I2C slave but I would be more interested on having only one LTC4331.

    I would like to know if it's possible…
