• AD5235 maximum voltage

    I use this AD5235 : https://www.analog.com/media/en/technical-documentation/data-sheets/AD5235.pdf and I would like to know if I can have more than 7 V between Va and Vb ?

  • AD5235 Sierial Interface

    Hi ,

    I have a quick question on the AD5235 serial data interface.

    I'm refferring to p. 17 in the AD5235 datasheet Rev.F.

    There it is said " if the count is not a multiple of four when CS bar goes high but ........'

    Quetion: Is it meant…

  • AD5235 not respond

    AD5235 not respond

    I'm using the AD5235 in rheostat operation, just to make a variable resistor.

    But the resistance between A1 and W1 is always 123k.

    When I connected the logic analyser to the SPI wires, I found that SDO is always cero, as shows…

  • AD5235: Programming

    The problem is very simple. The seriel programming Signals are provided by the
    FPGA, but the AD5235 doesnA?t store the value. I think I am not providing all
    needed signals or timings.  Is it possible to get an explanation how to connect


    I have problems when reading out the user EEPROM via SPI on AD5235.

    The Problems occur sporadically when read the address 0x1 or 0x2. All other Address can be read easily.

    I will explain the problems by reading the address 0x1.

    The Master sends…

  • AD5235: Daisy chain

    I am using the AD5235 Digital Potentiometer in my Final Year Project at
    University. I am going to try and daisy chain several of the Potentiometers
    together, but I am unsure where to begin. Do you have any technical notes on
  • Digital SPI Potentiometer Linux Driver Problem


    I am working with OMAPL-138 Linux version 2.6.37 and I am using the AD5235 digital trimmer.

    I can olny drive one trimmer rdac0, rdac1 insteda doesn,t work. If I write in rdac0 it writes also in rdac1. I think that the driver doesn't work well.…

  • Question about D-POT interface timing

    Hi all,

    I would like to know what is the minimum value of the parameter shown in figure.

    I suppose it is zero, but why is it not written in the datasheet?

    I checked several AD5235 trimmers. Someone has150uS other instead 0uS.
