• RE: Problem with Vref of AD7623

    Hi Karen,

         Yes, we have pulled down the PDREF and PDBUF.

          

          Additionally, we only provide power supply (including AVDD、DVDD、OVDD)to AD7623 during the debugging, then we notice that the voltage of REFBUFIN pin is 1.2V occasionally.


        The following…

  • About RESET Timing of AD7623

    Hi all, 

    I have a question about the AD7628.

    In Figure 32. RESET Timing of DataSheet(Page 21),
    t38 and t39 are shown.


    But In TIMING SPECIFICATIONS of DataSheet(page 5),
    Both t38 and t39 parameters define only typical parameters.

    Is the MAX value defined…

  • AD7623 reference buffer drive

    On the AD7623, how much current can the internal reference/buffer supply to an external circuit?  The data sheet has a schematic which indicates a 1 mA load on the 2.048 REF pin.  No spec was listed on the data sheet for the reference buffer current drive…

    Hi Jebas,

    PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…

  • RE: Measurement of pulse amplitude - suggestion for ADC

    Hi Henning,

         We have some I2C ADC interface that may fit your application, you may check the AD799x. Just like to ask on when are going to use the trigger feature, is it when the pulse amplitude hit some kind of limit or outside the range? I am also…
