• AD9833

    我现在选用AD9833来产生30-100KHZ的TTL方波,但AD9833只能输出正弦波和三角波,且最大幅值为0.65V.  我电路后级接了比较器,但是比较器不能输出波形,(AD9833波形正常),是不是AD9833波形太弱了需要先放大再进比较器呢??谢谢,盼解答

  • AD9833


    I would like to ask a question about AD9833.

    ANALOG DEVICES recommends that VDD pin should be connected 0.1uF and 10uF decoupling capacitors

    and CAP pin should be connected 0.1uF decoupling capasitor in datasheet Page.6.

    However VDD pin is…

  • EVAL-AD9833 board


    I have a Eval-AD9833SDZ board and also EVAL-SDP-CB1Z board to communicate with ad9833. But I need an information that how much lowest frequency I can get from AD9833 board by using EVAL-SDP-CB1Z board with ad9833 internal clk (25MHz).


  • RE: AD9833 Output Voltage Variation

    I would like to use a the AD9833 to produce a triangular waveform for a VCO but the output voltage of the AD9833 is 0.65 V. Is it possible to use a voltage amplifier to increase the voltage up to 6-7 V?

  • How do I simulate AD9833?


    I want to simulate with AD9833. So i need any simulation software. Please let me know is there any Simulation Software that contain AD9833 IC.

    Thanks and regards


  • Frequency Changing Time of AD9831 and AD9833

    Not sure how many time do AD9831 and AD9833  spend to change the output frequency? That is, if I want to change the output frequency, then what's the fatest timing for AD9831 and AD9833?

    Hope I describe my questions clearly.


  • AD9833 - Quasitrapezoidal waveform


    It is known that AD9833 Programmable Waveform Generator can generate Sinusoidal/Triangular/Square Wave Outputs. However, in our application, we need Quasitrapezoidal waveform. Is it possible to generate this waveform by programming AD9833?



    Designing an AD9833 into a product. Output will be 100 Hz to 1000 Hz. (sine wave). Using  5V supply.

    The AD9833 spec says the output voltage is max of 0.68V

    The ADIsimDDS simulation in my frequency range shows 2.0V peak-to-peak.

    What is correct?


  • 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…

  • 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…
