• 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.

  • Sawtooth signal generation by using AD9833

    Hi everyone,

    Can i generate sawtooth signal only using AD9833?I saw something that i have to use AD9833 and AD9834 together to generate sawtooth signal.Have to i use AD9833 and AD9834 together for generation sawtooth signal?

  • AD 9833 overclocking


        We want to generate a sine waveform of around 5-10Mhz for medical applications. The board was designed by a team member using AD9833 and 50Mhz clock. Now we realize that AD9833 gives a noise prone sine wave output at frequencys greater than 3MHz…

  • Can you change the output amplitude of the AD9833?

    As the AD9833 has a minimum output voltage of 38mV and a maximum of 650mV, I was wondering if it's possible to program the AD9833 to change the minimum and maximum output voltage.

  • some questions about the current of AD9833

    hello, what is the current of AD9833? I have try to find it in the datasheet, but I don't find it.

    and,Does the current of AD9833 change with the frequency? 

  • AD9833 Evaluation Board Labview Code

    Hi Folks,

    I am currenly doing an evalaution for the AD9833. Could I have a copy of the Labview code for the AD9833 evaluation board?



  • SPI Configuration for AD9833


    I use C8051 MCU to control the AD9833 and some other SPI devices.

    Except for the AD9833 I have to configure the SCLK with the clock pole idle at HIGH level state (CKPOL=1, CKPHA=0) and all other devices using CKPOL=0, CKPHA=0

  • 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
