• AD7822 questions

    I am implementing the AD7822 into a circuit. I was wondering if anyone can shed some light on my questions below.

    A) The data sheet says 2 MSPS. But by looking at the timing diagram on page 17, the only way I can see to get that sample rate is to not…

    Hi,

    I am looking for a 16b ADC  : pin to pin compatible to AD7822. Have you something to propose ?

    Thanks,

  • AD 7822 Confusing ~PD and ~CONVST

    Good day everyone!

       I'm about to use AD 7822 but as I read the datasheet, I got confused regarding the ~PD and ~CONVST. The AD 7822 powers up (getting ready) if ~PD is logic high OR ~CONVST is logic high (after #ns of ~EOC duration). The word OR here…

    Victoria,

    Look at pages 3 and 7 of the rev C AD7714 data sheet.  It's there.

    However, I would not do a new design with the AD7714;  it's very ooooold.

    Look at the AD7770 or AD7779.

    If you need PDIP, then use multiple AD7822 or AD7811.

  • AD7825: RD permanently low

    Q 

    The RD signal is it intended to transfer
    the data on the bus
    or can be tied always to low level?

     

    A 

    If you are using the AD7829 or the AD7825, the RD/ signal is essential for the
    operation of the device as the falling edge of RD/ is…

  • 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.
