    Hello

    I want to use AD9744 LFCSP package to generate a high quality signals with 90dB SFDR upto 10MHz, beyond it the SFDR should not be too bad.(around 50 to 60 dB)

    in Figure 49 and Fig 50  in the datasheet why they have used 100 Ohm termination at the…

  • AD9744 Test questions

    Hi all.

    I have some questions about AD9744.

    1.  Table 2 in the AD9744 datasheet, is the test condition AMPLITUDE 0dBFS?

     

    2.  Whether these indicators in Table 2 can be satisfied for both LFCSP packaging and TSSOP, especially when the sampling rate is 21…

  • AD9744 Output Transient

    Hi all,

    I am using the DAC AD9744 in a frequency counter circuit. I send in a clock signal to initiate the data conversion. However I see a spike of the frequency of the clock signal at the DAC output.  The yellow trace is the AC-coupled output signal…

  • AD9744 power on reset

    Hi all.

    I have a question about AD9744.

    Is there a power on reset in AD9744, if yes, could you give me some information about that. 

    How long will AD9744 reset after powered on with 3.3V?

    Best reagrds.

  • AD9744: Maximum sample rate

    Q 

    In the data sheet of AD9744, the update rate is given as 210Msps, but in the
    brief introduction and in the DACs table it is given  165Msps.
    Are 210 Msps and 160Msps tow different DACs? Could you please clear this
    ambiguity.

  • AD9744 input circuit

    Hello

    I have a critical problem in my PCB and need a urgently help. Please

    according to the AD9744's datasheet the input capacitance of a digital pin is 5pF.

    as per its IBIS model the DB0 pin in LFCSP package is 

    R=0.009777

    L=2.933E-09

    C=5.214E-13

  • AD9744的Clock Input setting.

    您好，

    我們使用AD9744作一個Voltage controller.

    在SOIC/TSSOP package的 pin 28_Clock腳，它需要輸入怎樣的訊號呢?

    在Datasheet中我不太明白這pin的要求是什麼。

    在32-Lead LFCSP package的CLK+-又是要輸入怎樣的訊號呢?

    Thanks.
