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?

Regards,

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…

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? 

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

Hi,

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!
