• About AD9432 ΘJc

    Hi, 
    I am considering the AD9432BSTZ-105 (52-Lead Low Profile Quad Flat Package).

    How much is the value of ΘJc of this IC?

    Best regards

    Q 

    Can you tell me what source impedance should I present
    at AD9432's input to obtain best SFDR and linearity ?
    Datasheet suggest 50ohm   22pF, is it the optimum ?

    Dear Sir/Madam,

    We are designing with your ADC AD9432 for our product.

    So I have a  question.

    As for your datahseet page.15 Fig-29 my enclosed, I can see the matching resister and capacitor between AD8132 amp and AD9432 AIN and AIN/.

    1) 50ohm and 22pF…

  • 请问用AD9432采集10M频率信号，能否有方法控制采集若干周期的信号发送给处理器而不是采样全部信号周期。

           目前我们希望使用该AD采集芯片采集外部晶振的频率信号，但是只需要采集若干周期进行分析即可，所以希望通过程序或者外部电路来实现这个功能，希望解疑答惑。
