• RE: AD9220

    this seems to be some sort of coupling in the board. 

  • RE: AD9220 problem. It shows random zero values.

    it looks to be a digital timing issue on the data capture side

  • AD9220问题

    AD9220在用FPGA控制时是不是可以直接用PLL产生的10M时钟就可以?我使用内部参考2.5V,将输入端与地短接时,输出的数据是0B80跟0380(13位位OTR位),输入一固定的电压值时输出的数据也不是固定的值,而且数据差别很大。这是怎么回事?

  • AD9220: DVDD explanation

    1/ What does DVDD from 2.7 to 5.25 mean ?
    2/ Is it possible to work with a DVDD=3.3V ?
    3/ In this case, which clock level has to be put : 3.5Vmin/1.0Vmax ?

  • AD9220: clock input level

    In AD9220 datasheet, the DVDD determines the digital output level. For CLK
    input, the high voltage level should be larger than 3.5V. Is it true for 3.3V
    DVDD power supply? I use 3.3V level clock and would like to know whether it is
    OK…
  • AD9220 differential input

    I have a differential signal  in a range of 2V( between 0.5V and 2.5V) . The average voltage around which the differential pair  swings is set to 1.65V.

    May I use the ad9220 ADC?

  • AD9220 and analog voltage offset

    Hello

    Hello.
    I have an analog signal coming from a sensor to the AD9220 between 17 and 19V and at a frequency of 200Khz.

    That means that my analog signal is between 17 and 19V

    I need then to create an offset of -17V in the way to be able to have the…

  • AD9220 Logic Input level

    Hi,

    Please tell me the logic input level (VIH / VIL) of AD9220 at DVDD = 3V.

    Thanks,

  • AD9220 simple AC interface

    采用datasheet里的simple ad interface接口电路。 我的信号频率在5kHz-500kHz之间,C1=0.1uF, C2=10uF, R=100K,  Rs=20欧姆,运放为AD817,运放供电+12,-12V。AD817输出有信号,经过C1//C2后,信号没有了。请问datasheet里的这个电路对C1,C2有什么要求?对信号幅度和频率有什么要求?

  • AD9220输出格式问题

    这是AD9220数据手册中的输出格式,这意味着它的转换范围是 0~VREF吗?
