• RE: AD5780 & No-OS Driver

    Hi Dan,

    The reasons for the code change was just to use the AD5780.c/.h files instead of the AD57XX.c/.h files, as when initially ran the AD5780 files produce the errors (file paths have been edited):

  • AD5780 Help!

    I'm unable to operate/control AD5780 chip residing on Eval Board (Eval-AD5780_90SDZ). 

    We are communicating with AD5780 DAC via McBSP module on TI-F28335 DSP chip.

  • RE: What the difference: AD5780, AD5781

    Hi byliu,

    The AD5781/AD5791 offer better accuracy (INL and DNL for example) compared to AD5780/AD5790.

  • AD5780和DSP采用SPI接口通信问题

    ADI的工程师们:您们好!!!

            我的测试电路具体方案如下:利用DSP28335的SPI接口与AD5780芯片通信,但在实验过程中出现个问题:在给DSP初始化上电的时候,AD5780的输出模拟量为-10V左右(外接电压基准为:±5V),请问为什么输出为-10V呢?AD5780的PDF手册上不是说上电之后是默认为0V吗?还有一个问题:是否需要对AD5780的控制寄存器先进行设置之后,才能正常工作呢?谢谢!!!

    Hello,

    I am not able to find the Arduino implementation in the ADI repositories. The generic driver can be found at the wiki link you provided. I will try to answer your questions the best I can:

  • RE: nanoDAC with more than 16 bits?

    Doan,

      We only have eight DACs >16 bits.  The small package is a problem.  The die gets pretty big

    w/ a lot of bits.  Look at the AD5780, AD5781, or AD5680.  They are different in terms of accuracy,

    resolution, and monotinicity.

  • Questions on SPI and RESET of AD5780

    Hi all,

    I use the AD5780 to drive a laser and for safety reasons, I use the RESET signal to put everything off.

    However, I found that after a RESET (going up) it takes about 25μs before the chip accepts a new command. Is this correct?

     

    Thank you very…
