• AD9822: SHA mode

    We’re using the AD9822 in the SHA mode, and providing a bias to the ‘offset’
    pin of about 1.7V.  This bias is derived from a potential divider, with a 4K7
    resistor and a 2K5 resistor.  We’re only using two channels of the 9822, the…

  • AD9822: External reference

    Thank you very much for the information. I understand that the converter
    range is two times the difference of (CAPT-CAPB). Are there restrictions
    on the absolute voltage level of CAPT or CAPB? Well, certainly between 0
    and +5.0V, but, for example…

  • AD9822: O/P data in 3 channel mode

    I have a problem with an ADC. I use the AD9822 analog / digital converter with
    the TCD2558D CCD sensor. This CCD sensor is 5340 dots by 3 colours.

    I use the ADC in 3 channels CDS mode. This ADC is programmed to switch data in
    the order "red, green…

  • AD9822 Output code

    Hi,

    I am working on the AD9822 CCD signal processor in bench and verifying its functionality in 1-channel CDS mode.

    My input signal is CCD waveform with reference level at 2V and data level at 1V at 1MHz frequency.

    I have programmed the offset voltage…

  • RE: AD9822 noise

    Hi,

    I am also working wiith AD9822 and went through your schematic. I can see that you have used some "Component_1" for the CDSCLK1 & CDSCLK2.I guess it to be some buffer IC. Can you please help me with the reason for using the same in your schematic…

  • RE: AD9822 output code

    Hi Barnes,

    Thanks for replying and helping me.

    I verified the digital levels are at the DRVDD voltage.

    I find the output of my code drop to random 0V. My input signal is CCD signal with reference to data level as 1V. 

    Below is the waveform captured at…
