• 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 am trying to use an AD9833 to generate a square wave. I am very new to electronics, and am having trouble understanding the MCLK pin. What hardware do I need to feed this pin? Will an NE555 do the trick?

    Thanks for any help!

  • AD9833 Amplification

    Hi. I am using an AD9833 as a signal generator but the output is only less than 300mV but I need to have at least 3 V. How do I ampify to signal like this? 

  • 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?


  • 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).


  • AD9833 using NI 8451


    I am using AD9833 to generate sine wave of centain freq and NI 8451 to write data to AD9833.

    we are using EVAL-AD9833SDZ evaluation board in place of AD9833 and writing the below data to the control and freq register,


    0x2100—Control Register…


    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?
