• AD5669R

    I need clarification on the Datasheet of AD5669R for the read operation, in pate 22 seems to imply that I don't require the Frame2 or Command Byte bu the Figure 52 does have it. It seems to me that I need it but the chip is not responding to a read operation…

  • DAC AD5669R

    hello everybody, I have question for DAC , IC AD5669R  its output Vout A~H can output  Sin wave with different amplitude for each output pin?

    thanks you very much 

  • AD5669R I2C high speed

    The datasheet (Rev A, pg 21) says "The AD5629R/AD5669R support standard (100 kHz) and fast (400 kHz) modes. High speed operation is only available on selected models. See the Ordering Guide for a full list of models."
    There is nothing on the…

  • error with AD5669R



    I use a AD5669-1 in my design, and I meet some strangeous errors that confused me.


    I configure the input register as follow.

    1, start

    2, configure Internal reference;

    3, configure DAC channel A;

    4, configure DAC channel C;

    5, configure…

  • AD5669R, accuracy vs offset error

    Hi there,

    I am a bit confused about the offset error and the accuracy of the DAC AD5569R. The value of the LSB should be 5 / (2^16) = 76 uV. So according to the datasheet, page 3 the accuracy is 8*LSB = 0,6 mV. But the offset error is 6 mV. Why do you…

  • RE: Send Analog pulse to the motor drive using AD5669 I2C module

    Hi ,

    Do you already have a controller? Which part exactly are you having difficulty?

    Important things to keep in mind to make your setup functional:

    -proper connectivity with the controller  and also the supplies

    -learn the basics of i2c, page 22…

  • RE: AD5669-1 "Invalid argument" when reading/writing _scale sysfs attributes

    Okay, that's what I had understood from the datasheet. The first paragraph of the "Internal Reference" section on page 21 is somewhat confusingly worded:

    "The AD5629R/AD5669R have an on-chip reference with an internal gain of 2. The…

  • Which package device is populated on the AD5669RSDZ eval board?

    Please could you let me know which package device is populated on the
    AD5669RSDZ eval board. This is not clear in your documentation.


    The 16 ld TSSOP is the package option used on AD5669RSDZ eval board. You can
    find a photo of the AD5669RSDZ…
  • RE: Sine wave generation


    Your application would require more programming on your side. The software will be the one to tell the converter on how much it would need to change the outputs.

    As for the DACs, You may want to take a look at AD5629R or AD5669R. They have 8 channels…

  • RE: nanoDAC-What are nanoDACs?

    nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.

    nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…
