• 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 Disy-chain Command


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

    I would like to know command operation.

    At 1st step initialize.

    1st      2nd     3rd

    800001  800001  800001 x3

    2nd step Output1

    000000 000000 11FFF0 Output OK

    3rd step Output2

  • 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…

  • 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…

  • AD5686R/AD5685R/AD5684R transfer function error?

    Revision C of the AD5686R/AD5685R/AD5684R datasheet shows the transfer function of the device as

    Vout = Vref * Gain * (D / (2^n))

    It then goes on to say that the valid code ranges are as follows:

    0 to 4,095 for the 12-bit device.

    0 to 16,383 for…

  • CONNECTION ERROR: AD5686R Evaluation Board was not detected

    SDP board(EVAL-SDP-CS1Z) is detected by both software and the led on SDP board blinks. But error AD5686R Evaluation Board(EVAL-AD5686RSDZ) was not detected appears after that.

  • 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: How to enable the AD5684 output analog signal by channel A


    Accodding to AD5684R Quick Start Guide》,I think the pin LDAC tie low permanent is OK.

    And I have transmited command 0011 to AD5684,but I still detect any output from channel A.

    I hope you can give me an example code of driving AD5684,or tell me…

  • 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…
