• AD9833的高温替换芯片哪个比较合适?

    之前用的是AD9833,但是最高耐温是105℃。

    现在想找一个耐温125℃的,

    找了AD9833-EP,AD9837两个,和AD9833引脚一样的,

    现在想问的就是AD9833-EP,AD9837和AD9833除了耐温还有什么不同吗?

    选择哪个作为替换比较好呢?

  • AD 9833 overclocking

    Hi,

        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…

  • 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?

  • 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.

  • SPI Configuration for AD9833

    Hi,

    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   

    I make 2 different…

  • 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

    I have some problem with AD9833.

    My MCU is DsPIC30F4011

    I send SPI data ex.

    AD9833setFreq(100000);

    void AD9833setFreq(long freq )
    {
    long FreqWord = (freq << 28) / 25000000L ;
    int MSB = (int)((FreqWord & 0xFFFC000) >> 14);
    int LSB …

  • AD9833

    Hi,all.

    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…

  • AD9833

    Hi,

    I am using AD9833 to generate a 134kHz square wave. MCLK=11.0092MHz. The output square wave does not have uniform period. Eight pulses have the same period and then the next one has slightly longer period. Later, I found out the difference is one…
