• AD9833 clock sync

    Hi All

    I would like to sync 2 AD9833 together and just change the phase of one of them relative to the other in 1 Deg increments.

    I see it is possible to use multiple AD9833 on one Arduino, but not sure if they are able to sync together like described…

  • AD9833 - Not oscillating 300mv O/P


    I've pretty much copied the UG-272 schematic and made a board up, but when testing I just get a static 300mV output.

    On power up there's 300mV, drops down to about 100mV, then down to 0V and back to 300mV.

    I've followed the AN-1070 and followed…

  • RE: AD9833-CLK function

    Hi, Imtiyaz,

        Interestingly, in spite of the difference in description between the ML2036 & AD9833, the serial programming waveforms are very similar between the two products (ML2036 datasheet, p7 & AD9833, p3), when FSYNC on the AD9833 is used for LATI…

  • RE: Looking for an IC that makes a +/- Voltage Sinusoidal Waveform with variable frequency (AD9833)


    Yes. The AD9833 is capable of producing a +/- voltage sinusoid. Here is the AD9833 evaluation board user guide that you could use as a guide. To ensure that the waveform is centered around 0, just add a coupling capacitor at Vout.

    Best regards,


  • AD9833: Difference between AD9833 and AD9834

    I want to use one of these two DDS chips (AD9833/AD9834) to generate a square
    wave signal of 10...90kHz from a 7.2Mhz clock. All I need is a square wave
    output. I therefore don't need the DAC running but intend to use the MSB output

  • RE: AD9833 Perfect Square wave but no Triangle or Sin

    I have concluded that the AD9833 I had been using was ether faulty or Damaged and would not produce a SIN or TRIANGLE Waveform. By replacing the Chip with a second AD9833, it worked right off the bat with no change to the code I had been using.


  • RE: 3 x 400Hz Sine Generator

    Thank  you for this information, in fact, this component corresponds to our  needs, but do you think it is possible to achieve what we want to do with 3  AD9833?
    Is there a way to synchronize 3 AD9833 way to have a phase shift of 2Pi / 3?

    Thank you in a…
