• AD5422 SPI timing

    I have a question regarding the SPI timing for the AD5422 in Daisy Chain mode vs. Read/Write in normal standalone mode.  Here is a copy of the Timing characteristics from Rev O. of the datasheet:

    Question 1:  Why is T5 in write mode 5uS, while in daisy…

  • AD5412: Connect the AD5412/AD5422's Iout and Vout pins directly together

    Is it possible to connect the AD5412/AD5422's Iout and Vout pins together, as
    is possible with the AD5755?


    The AD5422's Iout and Vout can be connected together but to prevent additional
    errors in Iout mode there are some pre-requisites…

  • The AD5420/AD5422 does not seem to function as I expect when using external RSET?

    The AD5422 has a feature whereby, when the external RSET is being used, the “REXT” bit (D13 in Control Register), should only be set in the same write command as “OUTEN” bit (D12 in Control Register) gets set.

    Alternately, "REXT…

  • RE: AD5422 incorrect output issues.


    Sorry for the very long delay on this but the problem seems to go away then comes back quite randomly, we have started having this issue again.

    From further investigation we have found that the Iout is fine its just that the voltage output is always…

  • AD5422 output issue


    Im trying to get the AD5422 to work but the output stays constant at 1V no matter what i write into the data register.

    The output is 0 to 5v range.

    This is my schematic:

    I connected -Vsense to ground and +Vsense to Vout but no change.

    My SPI looks…

  • About AD5422 0mA no-load output, does the FAULT pin issue a FAULT alarm?

    About AD5422 0mA no-load output, does the FAULT pin issue a FAULT alarm?

  • does AD5422 with a thermal shutdown feature ?

    AD5422 configure as 4 ~ 20mA output, but the output will be shutdown in harsh environment, I want to know if AD5422 with thermal shutdown feature.

  • AD5422 - Output voltage not getting set

    I am using AD5422 in our Design.  All the Signals are meeting the Datasheet requirements. Still on VOUT pin we are not getting any output voltage.  

    The Schematics of the DAC is as shown below:

    Kindly let us know, if there is any issues in the Design.

  • AD5422 not working


    I'm trying to get an AD5422 working. I can't get an output signal or register data from a readback.

     Here it the schematics I use:


    DVcc = 3.36V, AVdd = 11,93V, AVss = 0V, Clear = 0V;

    Vout stays always about 16mV.


    1. I removed IC13, R57 and…
