    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,

    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.

    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…

    Hi Miek3886,

       Please refer to response to each question below.

       1) If I tied ~PD permanently high to Vcc, does that mean the AD 7822 will not power down at all even if after ~EOC, ~CONVST is low? Is the state of ~CONVST ignored regarding power down if…

    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.
