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…
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
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
There seems double specification about reset duration on datasheet.
Page 6, Timing Characteristic says RESET Minimum Pulse Width Low is 4.8 or 6.2 ns.
On the other hand,
Page 27, HARDWARE RESET says:
It is necessary…
I am not able to use the RESET pin to set the DAC outputs to default values before I program the DAC.
Here is what I do :
- RSTSEL is set to VLOGIC, because I want a default output voltage of 2.5V
- t0 : DAC V_LOGIC is supplied with 3.3V ; RESET…
Thank you for your answer.
Your advice is very useful to me.
I have additional questions.
It is described at AD5791 datasheet
T17 : /SYNC rising edge to output response time(/LDAC tied low) (datasheet Rev.D table 4)
I would also recommend for you to have a look at AD5672R/AD5676R which is a newer 8-channel DAC.
You have to send DCEN bit to all devices to ensure all parts are enabled for daisy chain mode.
Can you check this EZ thread:
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?
