    Dear Sir/Madam,

    I wonder whether the FCO signal of AD9272 and DCO signal will change with the sampling frequency.

    I've got some doubts regarding the AD9272 design. All my questions are on the attached schematic file.

    I would appreciate for the suggestions.

    Best Regards,


  • AD9272

    Hello, i´m using chip AD9272, I have a question...

    I only want to use one channel, and i don´t know if i have to connect all the pins of the supply ( AVDD1 and AVDD2) or if  i can connect only some of them , that is, i´m using the channel A, so i suppose…

  • AD9272 DCO


    I am evaluating the AD9272, using the AD9272-EBZ evaluation board.  When I scope the DCO_P vs DCO_N I see nothing on the scope (sample interval 5ns).  I can see a 40MHz on FCO.  I have disconnected the SPI jumpers so understand that the chip should…

  • AD9272 HPF


    To calculate some values, I would like to sample low frequency (frame rate) square wave, but I find AD9272 cannot capture frequency lower than ~400Hz. Is there any way to disable high pass filter so that I can record low frequency signals?


  • AD9272 active impedance matching


    I was reading the datasheet of AD9272 and I can't understand what does it mean with "combination" of Rfb1 and Rfb2 (of Figure 38) to give an equivalent "Rfb" (in equations 1 and 2), when they talk about active impedance matching. Also, what does…

  • Ultrasound - AD9512/AD9272


    I'm prototyping an ultrasound scanner based on AD9272 and I've got some

    problems/questions. First, I would like to tell you some details about my project:

    1) HV TX circuitry is not assembled yet on my PCB, it will be the next step on…

  • AD9272 source code


    I have the AD9272 evaluation board connected to a HSC-ADC-EVALCZ, can you provide source code for the CY7C68013A used on this board?

    Also do you have FPGA code, I could not see it in ftp://ftp.analog.com/pub/HSSP_SW/fpga.

    Lastly do you have any…
