Hello

I'm currently working on daisy chaining 2 AD5672R DACs together, I've sent in the command(1000 and DB0=1) to enable the daisy chain mode but it doesn't seem to be responding to the command. I've attached a snap of the chipscope signals and i believe…

The AD5672R output drive capability is stated as 15mA max, is this source and sink or source only, I would like to be able to sink a small amount, <1mA, and would prefer not have to add additional buffers

Hello, i have a problem... We have a card that we use it with the ad5672 and everything work fine. I took the design and put it in my card and the ad5672 not respond, i have the same firmware on both cards. 

The only difference is i put 3.3v on both VDD…

Dear Madam or Sir,

I try to use the 0011 command of the AD5672R. I'm not sure about what it does.

According to table 16 of the data sheet I would expect, that the input register and dac channel addressed by the address field (DB16 to DB19) get written…

Question: Figure 46 on Rev B. of Datasheet of AD5672R/AD5676R.  What is the test condition for this figure?  One DAC change at a time and they are all compiled later?  Is this just one DAC changed once or multiple times?

Thanks,

John

使用STM32F103的SPI驱动AD5672r,始终没有输出，用示波器测试时钟（sclk）和SDI波形如下图，程序固定向2通道发送0x00f3,命令是0011, 即“写入并更新DAC通道”，24位命令字为，0011 0001 0000 1111 0011 0000,从波形上看没有问题，但

就是没有输出，请各位大神帮忙分析一下。
