• AD5640: Increasing gain

    If I want an output from 0V to 3.3V (in a system with a 3.3V supply) can I put
    a resistor between the output pin and the FB pin to increase the gain from 2 to
    2.6?

     

    This is not the best approach.  The device is internally trimmed to comply…
  • EVAL-AD5662/AD5660/AD5640/AD5620

    Hi everyone!

    I'm using EVAL-AD5662/AD5660/AD5640/AD5620 and have AD5660 as my DAC and I noticed that there are grounding problems to the AGND and DGND pins of the evaluation board. It is said in the datasheet of the evaluation board that the analog GND…

  • AD5620 or AD5640- Using Vfb to control the DAC output

     

    Hello,

    Using the AD5620 or AD5640 with Vref=1.25v.

    1- According to the datasheet Vref pin must be shorted with Vout and it gives a maximum output voltage of 2xVref with resolution of 2xVref/2^N.

    Question: Is there a possibility of connecting Vfb…

  • RE: looking for reference circuit of AD9834 to op amp

    Hi Miguel,

    The specifics of some of the parameters are still to be determined but the supply voltage and output range would be about 20V, max current output could be about 100ma, Not sure about the impedance.  It would need high amplitude resolution so…

  • AD5620 Model Options

    i have a question about AD5620 Model Options.

    what difference between AD5620A..., AD5620B... and AD5620C...? Difference is only in relative accuracy between models (A the best?)

    next, AD5620-2-3 parts include an internal, 2.5 V, 5 ppm/°C reference,…

  • 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…
