• AD7400 : output waveform


    I have a question about the AD7400.

    I connect the AD7400 with the FPGA.

    The following waveform is the test input signal to the AD7400.

    The signal is a sine wave of 100mV(1Hz) with the noise.

    The following waveform is an output of the Sinc3…

  • RE: Bitstream from EVAL-CED1Z

    Hi mhay,

    The AD7400 software on the CED board does not have the functionality to pass the raw bit stream data. The AD7402 which is the next generation to the AD7400 has software routines to read the raw data. It needs an SDP-H board though.


  • (AD740*)What is the difference between AD7400 & AD7401 & AD7402 &AD7403?

    Hi !

    Our customer have interesting in AD740*.

    And they want know what is the difference between AD7400 & AD7401 & AD7402 & AD7403.

    Can you explain the difference?

    AD7401 is AD7400 external clock version.

    AD7403 is AD7402 external clock…

  • AD7400 rush current

    Hello All


    Please let me know rush current specification of AD7400 or give me related date.


    We use AD7400 in our system now.

    At the moment, there is no problem with our system for rush current.

    But , datasheet does not describe rush current parameter…

  • RE: AD7400 power supply

    Hi Terumasa,

    Ensure that the absolute maximum ratings are not exceeded or violated, then there should be no issue. Additionally, the device should work fine as long as the analog inputs are applied after the supply establishes the 5 V output.


  • AD740x maximum input to output delay

    What is the maximum input to output delay of AD7400/AD7401 provided that a 4 MHz clock signal is provided? Is there a certain way to control exact sampling point?

  • RE: Current Sense help needed!

    Hi Pantelis,

    Sorry for getting back late. I've talked to several applications engineers and they recommend the AD7400 and AD7401 for your application. These products are isolated sigma delta converters designed for isolating current sense in motor control…

  • RE: Save RAW datas from EVAL-AD7400EDZ ?

    Hi Mickael-

    I moved your question about the AD7400 Evaluation board to the Precision ADCs community.  Someone here should be able to assist you.
