• AD9786: Reset timing

    For our application we are using the DAC AD9786 as a straight DAC, that is,
    with the default settings. We are not using the SPI interface either. We want,
    however, to Reset the DAC each time the system is reseted. For that we would
  • AD9786: Propagation delay

    What is the dependency of the propagation delay and settling time of the AD9786?


    Propogation delay is dependent on mostly digital filter configuration since
    each filter has its own group delay depending on #of taps (i.e. group delay=FIR…
  • AD9786: Thermal pad connection

    1.) Pg 9 - Pin 2 is DNC
    Pg 47 - Pin 2 is labeled as LPF in the application circuit.

    2.) Pg 55 - Must the thermal pad be connected to AGND or DGND?


    1) DNC = Do Not Connect

    My guess is that figure 88, page 47 is a throwback to the…
  • AD9786 - three questions

    Dear Sirs,

    Please answer:

    1. On page 5. of the AD9786 datasheet it is written:

    Gain Drift (with Internal Reference)      ±4 ppm of FSR/°C

    Reference Voltage Drift     ±30 ppm/°C

    Is it correct?

    2. What is the gain drift with EXTERNAL reference?

    3. Is it possible…

  • AD9786: Current output voltage calculation

    I found a problem with one of my customers where AD9786 full scale output power
    under single tone test condition is only 3 dBm, much lower than the specified
    value 10dBm, so they would like to confirm if max. output power of AD9786 is
  • Basic configuration for DAC AD9786

    Could someone provide a basic configuration of register for DAC AD9786 to make it  work In such way that i give the data input and get the data in analog form?

  • AD9786 maximum analog output frequency


    What is the maximum analog output frequency we can generate from AD9786 DAC in 1x,2x,3x and 4x interpolation modes?

    Max input data rate : 200Msps.

    Max output update rate : 500Msps.

    How to determine the max output frequency from above data?
