Confirm whether we can use AD574ASD/883B in the design

@

Hi,

We have selected part AD574ASD/883B (ADC Single SAR 12-bit Parallel 28-Pin SBCDIP).

In Analog Devices website it is showing that all the parts of family AD574ASD are NRND (Not Recommended For New Design).

Please confirm whether I can go ahead with the part AD574ASD/883B, Is there any difficulty in procurement and getting future technical supports during functionality testing If I choose this part.

Regards,

    Hi Vijetha,

       I will need to confirm it first and get back to you about AD574 not recommended for new design because there is conflict with the ordering guide it says it is still in production. Meanwhile may I know what application that you are trying to build on for the AD574? Maybe we can suggest an alternative that may fit to your application. ADI has wide range of ADC that may cover many application.

    Regards,

  • Thank You for the response.

    We are going to use it in our PCB design for Temperature Monitoring system in which Temperature sensors feed inout to ADC and output of ADC is sent to Xilinx FPGA for further processing.

    As our customer specifically suggested this ADC part, we need an equivalent part number having same features of AD574 (If AD574 is NRND).

     

    So please confirm can I use AD574 in my design. If In cant use it, please suggest a suitable part thatt hasall the features of AD574.

     

    My only concern with part selection is that I should get a proper technical support during board bring up (if needed during Testing). We had very limited technical support for one of the part selected in our previous design because of NRND issue. So this time  we would like to confirm the NRND issue before part selection itself.

  • Hi,

    With respect to Temperature, We need Industrial Grade Part that should be operational in the temperature range of -40 to +85 deg C. 

    There is no specific requirement on ceramic package, We should be able to assemble it on PCB.

    Yes we can ue either serial or parallel output interfaces, but we prefer parallel outputs.

    Regards,

  • Can you mention the full ordering part number of AD574 series?

  • Do you need a military part(883BB) or just military temperature?

    Do you need a ceramic package?

    I'm assuming with an FPGA, you can accept parallel or serial interface?
