• AD7400A inside delay

    How much is the internal delay when I input a pulse?

    I think that a delay produces 30ns in an ISO part.
    How many will the quantity of delay in the ADC circuit part be?

  • AD7400A:  Can this device accept both differential and single ended inputs, datasheet is not clear?

    The AD7400A specifies an analog input range of +/- 200mV and a specified full
    range of +/- 320mV, which I interpret as a bipolar input. When looking at the
    abs max ratings, it can only be on the negative side GND -

  • RE: DC current shunt monitor for upto 250 VDC loop

    Hi Jatin,

    The AD7400A and the AD7401A parts are our parts that are targeted at shunt current monitor applications.

    They accept signals in the +/-250mV range and have in-built isolation based on ADIs iCoupler technology.

    The output of the AD7400A and…

  • RE: medical ADC isolation

    Hi Natanel,

    The internal clock on the AD7400 and AD7400A is used to clock the converter internally and also to allow the user to clock out the data bits from the modulator into an FPGA for example or other receiving device.

    This clock typically runs…

  • RE: The distance between ADUM1400 components

    Hello anpoit00,

    I assume you're asking about the distance between the ADuM1402 and AD7400A (see the marked up figure I've attached). There's no requirement in terms of the isolation rating, but you might want to leave space to accomodate an increased…

  • Bitstream from EVAL-CED1Z


    I am a student of the Engineering School of Fribourg in Switzerland. I’m using
    a EVAL-CED1Z evaluation kit in combination with a AD7400A Delta-Sigma Converter
    for a school project. I need to know if it’s possible to store the bit-stream

  • RE: ADC evaluation board choose

    Hi Yake,

    I have attached a list of some of the ADCs that fit your criteria of 2MSPS sampling rate or higher at resolution of 12bits or more.

    You may also wanted to check the ADI website and do a parametric search (http://www.analog.com/ps/psthandler…


    Hi Ignacio,

    Sorry for getting back late. We have an analog isolator circuit which you may want to consider. It is implemented by using AD7400A, an Isolated Sigma-Delta Modulator.  Here is the link of the reference circuit:
