• AD7671

    Can you suggest the alternate IBIS model which can be used for AD7671 for SI analysis ?

    We also require Rise/Fall time for AD7671.

  • AD7671 Output has step

    Hi,

     When I use AD7671 to convert signal (1Hz to 1kHz), I found steps in the output.

    Attachment figure 1 is the waveform, where green line is input of AD7671;yellow line is the output of AD7671 (a DCA output, the DAC operated well).

  • AD7671 step

    Hello 

    I connected to input 0 V - code from AD7671 is 32463. It is fine. 

    But when I repeat request the code is

    32463 32591 32591 32463 32591  .... 

    32591 - 32463  = 128  - Where is low signif. bits ?? 

    I checked with serial and parallel data mode.

    My parallel…

  • problem with AD7671

    hi there,

                 I am using AD7671 ADC in one of my project. I accidentally supplied analog signal(13V) to the ADC without powering the ADC. Now this adc is behaving abnormally.  I am able to get accurate data till 2.5V input after this range the ADC doesn…

  • AD7671 interfacing with ADSP21369

    Hi,

    I am currently working on interfacing AD7671 with ADSP21369 using SPI communication protocol. Here ADSP acts as master and ADC as a slave. I have configured all the spi registers, srus. I am struck how to use ADC's CNVST pin to read the converted…
