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？

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?

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…

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.

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? 

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?

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…

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 …
