Hey all;

This is my first discussion here at engineer zone:

We are using the DAC AD5686 daisy chain mode to end with 32 channels for an application.

I was wondering if between the DOUT of one DAC and the DIN of the other DAC a pulldown resistor is…

Dear all.

I am using AD5686 DAC for audio output.

It is working properly.

However, in rare cases the DAC output is not updated and the output completely disappears.

It only happens occasionally(about once in 1 to 2 weeks) and I can’t reproduce the problem…

Hi,

I wanted to sweep the output of the AD5686 from zero to full scale, unfortunately the provided the software with the evaluation board can only process one code at a time.

Is there a way that i can access the labview code of the evaluation software…

Hello, I'm Nikolai Ehrhardt from Germany,

I got problems with the timing of the AD5686,

I'm giving a falling flank on the Sync line, then the ATmega168 starts to transmit the dataword via USART in MSPIM beginning with 0011 for LDAC independant commands…

AD5686不能输出转换结果，试了好多配置都不行，示波器测得的时序和数据手册时序也一致，我是用FPGA的输出引脚直接给AD5686提供时钟信号SCLK，是不是因为这个原因导致的啊？

Hi

I have a question about AD5686 (4ch 16bit DAC).

Could you let me know how should I think about REF selection.

AD5686 is multi ch DAC but it doesn't have REF buffer inside.

So, I am concerned that REF selection affects to accuracy of each…

I am unsure how to compare the settling times of the AD5544 and the AD5686, due to the different way in which they were measured.

The AD5544 goes from 0 to full scale then back to zero and has a settling time of 0.9us to plus/minus 0.1% full scale. The…
