• AD5685R external reference


    Can AD5685R use 4.096V or 2.048V external reference ?

    My customer would like to use AD5686R for 14bit, 4ch and  small package at 4.096V full-scale.

    The datasheet says that  impedance of REF pin is very low and  the internal reference 2.5V is enabled…

  • AD5685R VREF pin


    When using the internal reference for only internal DAC, not for external circuits,  Should VREF pin be decoupled to GND with something capacitor for the internal reference? Or Is it OK to be opened?

  • AD5685R Reset Select


    I am using the AD5685R in a circuit in which I have RSTSEL tied to Vlogic which places the DAC in a midscale output upon toggling the ~RESET pin low.  However during testing, when ~RESET is low the DAC output is zero volts then when reset goes high…

    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…

  • AD5686 Vlogic level and GAIN pin


    I am looking at the datasheet of the AD5686/AD5684 (revision C) and there are two somewhat unclear topics I was hoping someone could help me with.

    1. Vlogic level in relation to Vdd:

    On page 6, note 1 says that the SPI speed of 50MHz is only valid…

  • RE: AD5685 start up reference setting

    Hi, Osamu-san.

    Apologies for the delay. Are you referring to AD5685R? There is a possibility that the part has been damaged. Have you checked if the part is still functional? Will you be able to check the voltage level of the internal reference and check…
