• Wich Supply Voltage for the AD688 is necessary?

    Hello community,

    I need a high precision reference voltage for my 16 Bit DAC, so i decided to use the AD688.

    In the Datasheet the IC is supplyed by a voltage of +-15 V, but in my circuit I have only +-14 V or less.

    Is it possible to use the AD688 with…

  • AD5791 Reference configuration

    I will be using the AD5791 DAC for precision waveform generation (~10kHz), but I need to be able to supply either a +/-5V range or +/- 10V range output.  My question is, in general would it be better to adjust the gain via the reference buffers or via the…

  • AD688ARWZ: Operation guaranteed power supply voltage

    Hi,

    According to the datasheet, it appears that the AD688 is recommended to
    operate with a Vs supply voltage of ± 15 V.
    Is operation guaranteed at ± 12V?
    Best regards,
    Makio
  • RE: ad5791 glitch

    Hi

    We use AD688 as reference-ic for this DAC. Is that too bad?

    regards

  • DAC8412B Power up restrictions/limitations

    I am using a DAC8412B in an application and I want to understand if there are any restrictions or guidelines with regards to power up sequence.  I don’t see anything related to power up sequence noted in the datasheet, but comparing the possible power…

  • RE: AD5726 reference voltages and power-up sequence

    Hi Michael,

       


    1. The AD5726 datasheet says that the minimal negative reference voltage is -10V. On the other hand, typical application discussed throughout the datasheet utilizes +/-10V references. So it looks like the datasheet suggests working just…

  • RE: Suggestion for negative Vref

    Hi Kaos,

    We have only two references capable of negative output voltages at this time. These are the AD688 (+/- 10V) and the AD588 (+/- 10V, +/-5V). Neither are capable of a direct -4.096 V output.
