• 咨询 AD5317R AD5684R AD5685R AD5686R 兼容性 谢谢

    4通道SPI接口的DAC: AD5317R (10bit)、  AD5684R (12bit)、 AD5685R(14bit)、  AD5686R (16bit)



    1 这种封装的,这4种器件是 pin-to-pin可以替换的,是吗?

    2 软件也是兼容的,只是精度不同,对吗?

  • AD5684R Disy-chain Command


    On daisy-chain operation likes Fig 53 (AD5684R x3).

    I would like to know command operation.

    At 1st step initialize.

  • AD5684R daisy chain mode


    I would like to know daisy chain mode command on AD5684R 12bit.

    1000 0000 0000 0000 0000 0001

    It's OK?

    Will DAC address ignore?

    DB0 is not meaning DATA bit (D0) ?

    SDO doesn't carry any signal ,before processing this command?

    How should…

  • AD5686R/AD5685R/AD5684R


    I have just implemented AD5685R in a new design however when powering up the system the AD5685R circuit (TSSOP16) get very hot.

    If I strip of everything surrounding the circuit except for connecting 5V to Vdd and pin 10 (GAIN) and 0V to GND…

  • AD5684R/5R/6R, Gain terminal


    I would like to know which description is correct?

    Data sheet RevA Page 10 say "Gain pin connect to VDD".

    But UG-459 Rev0 Page 6 Figure 5 described Gain pin pull up to Vref.



  • Power-up sequence of AD5684R serise.


    Please let me know if there is "power-up-sequence" of AD5684R.

    "Absolute max rate"would be say no "power up/down sequence" ,I think.

    but the timing characteristic say 1.8<= VLOGIC <= VDD on a margin.

    it's just…

  • RE: Is there an Arduino library for use with the AD5687R DAC (SPI) ?


    No direct library available but you can re-use and implement necessary changes to the No-OS driver for AD5684R.



  • RE: Code example for AD8450 (+ADUC7061)

    Hi Emiliano,

    The AD8450 is an Analog Front End (AFE) and has a pair of analog control loops (current and voltage).  It is not a digital peripheral so there are no drivers for it. However, there is typically a pair of DAC's to configure ISET and VSET points…
