• AD5689R输出异常

    我正在调试AD5689R,出现一些问题:我使用一个FOR循环写入0 ~ 65535,通过命令0011写DACA 和DACB同时输出,使用内部基准电压,通过万用表测量发现:VoutA=0v, VoutB从2.5~5V输出。请求高人指教,谢谢

  • SDO pin of AD5689R?


    AD5689R will be on an SPI bus with other devices. They will share a common SDO line to the SPI master.

    Question, Is its SDO pin a tri-state output? Or, an external tri-state buffer is needed?



  • AD5689R the right choice?

    I am trying to choose a DAC for my design. The intention is to have the DAC to output a voltage reference 0V to 5V which have a minimum resolution of 12 bits. I wanted the DAC to be more versatile as it might be able to generate a simply sinewave or arbitrary…

  • Is power down cirsuits in AD5689R?

    Hello AD5689R include Power donw cicruit with normal and  three-state output mode. my question is.

    This mechanism can be used as a switch, for connect and disconnect DAC to amplifier?

    For example DAC is in tree-state,

    I set DAC on 2,5V over LDAC pin…

  • How Power-on reset work on AD5689R?


    I have several question about AD5689R Power-on reset and power up sequence.


    1)What function is the Command 0110 for this software reset ?

    Is it the same function for Hardware reset (/RESET) with RSTSEL pin? ,or register is clear/default?

  • RE: EVAL-AD5689RSDZ user guide and evaluation software


    AD5689R產品網頁的Evaluation Kits顯示是EVAL-AD5686R,


    於Google搜尋EVAL-AD5689R可以找到EVAL-AD5689R的user guide,

    因此想請問ADI網站是否可以找到EVAL-AD5689R的user guide及evaluation software,謝謝.


  • RE: AD5689 Maximum Voltage Reference Load


    Yes, you may use the internal reference voltage of AD5689R as an external reference voltage for AD5689.

    AD5689R can drive up to 10mA load and the  AD5689's reference current is only 90uA (using gain =1).
    hope that answers your question!


  • RE: [AD6589R]Does SDO pin go Hi-Z during SYNC high?

    Hi Sofy-san,

    Could you verify that this is AD6589R? It may have been a typo but you might be referring to the AD5689R but I could be mistaken. Could you verify this?



  • What is real noise performance of nanodac/nanodac+?

    There are many mismatches in noise characteristics found in datasheets of nanodac and nanodac+ families.

    Let's examine AD5689R one first.

    DAC output NSD (DAC code = midscale, 10 kHz; gain = 2) is 300 nV/√Hz and LF noise 6 µV p-p. With gain 2 and…

  • RE: Automotive and CRC feature DAC

    Hi ,

    We have AD5310 (single channel) and AD5689R (dual-channel) automotive parts but these parts do not have CRC feature.

    AD5755-1, AD5758, AD74413R, and AD5423 have CRC feature but not automotive parts.

    Is the CRC feature a must-have requirement…
