• AD5680 update anomalies

    Hi

    I am trying to use an AD5680 nanoDAC in a control loop whose output needs to be updated on the order of every 10 microseconds.  Unfortunately, I'm finding two problems:

    1) The output change does not occur for about 250 microseconds after the serial…

  • AD5680 not updating

    I have been using the AD5680 for several years.

    I am experiencing a problem recently where the output does not update. It is frozen, holding a last value written.

    I can see the data (chip select, SCK, SDO) with logic analyzer and all is normal.

    I can…

  • Problem Writing data to AD5680

    Hello All,

     

    I need some help on working with AD5680, I am writing configuration bits but no update i output it is always 0. Bellow I am attaching graphs at the input of AD5680 and schematic that we are using. I need some help to figure out what we are…

  • How to communicate with a AD5680

    Dear Tinkerers,

    for a project of mine I would like to start using the AD5680 Nano DAC 18Bit.

    To communicate with the DAC I require SPI.

    How to connect the right pins to the Teensy3.6, which pin goes where?

    SCLK=SCK?

    MOSI=DIN?

    CS=SYNC!?

    if so could…

  • AD5680 problems with writing to the inputregister (SPI)

    Hello,

    I have a AD5680 and I want to write to it's inputregister with SPI. But the outputvoltage dosn't change. The SYNC on the picture falls befor sending and rises after the last CLK. I use a frequency by 3,8kHz. Any ideas why the DAC don't accept…

  • Is it possible to use the EVAL-5680 with LabVIEW

    Hello,

    I have purchased an evaluation board for the AD5680, a Single Channel, 18-Bit, Serial Input, Voltage Output DAC.  I would like to use this in a single application, and therefore it would be helpful to simply use the evaluation board.   AD provides…

  • RE: Is a replacement for the LOGDAC AD7111 ?

    Hi msamera, and what about the 18 bit AD5680 ?

    I need to use it as a multiplier, with a reference signal near 5Khz.

    I don't like the last stage that provide the 2 less bits. I think that the final filter could disturb my signal.

    The documentation…

  • RE: nanoDAC-What are nanoDACs?

    nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.

    nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…

  • nanoDAC - Which DACs should be used for open loop systems and which DACs should be used in closed loop systems?

    It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.

    In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…
