  • AD7484 REFOUT

    1. How much current can I draw from the internal reference (REFOUT)? With REFSEL floating with a 0.1uF cap to AGND, REFOUT drops to 1.9V volts with a 4.7K load (0.5ma). Table 10 says the REFOUT impedance is 1 ohm.
    2. Fig 10 in the data sheet indicates…
  • AD7484 Minimum Conversion Time

    Can you tell me the minimum value of tconv for the AD7484 as it is not
    specified in table 2 of
    the datasheet?

     

    On the AD7484 (as with many of our parts), the conversion time is clocked
    internally and we specify the maximum time…
  • AD7484 Ouput drive capability

    What is the output drive capability of any output on the IC.  We are using a
    number of the same ICs in our circuit on a common data bus.  Unused devices are
    tristated.  We need to know the drive capbility of the devices outputs so that
  • AD7484: Initialization process

    I am working on a project and am using an AD7484 14bit SAR ADC.
    The device is running in connection with a FPGA, and later with a CPLD.

    In order to minimize the FPGA/CPLD design, I did not configure the 7484, i.e.
    I did not write any…
  • AD7484: Width of Reset pulse

    After reset of AD7484, when  CONVST signal is given by single time, the BUSY is
    always low. But when it is given a continuous pulse to CONVST pin, it works
    well. I found out that the problem is the RESET signal  provided for the chip
    is…

  • 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…

  • RE: ADC 12/14BIT, >2mS/S, Parallel digital interface

    Hi Meir,

    You may  want to check the ADI website and do a parametric search to filter the product display  base form your recommended specification.

    Here are some ADCs that might help  you start with, kindly see attched file.

  • RE: ADC used for single-pulse conversion

    Hi Postino,

    Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
