• 关于AD9203中REFBF和REFBF引脚电压

    在datasheet中 有描述到：REFTF and REFBF will drive the ADC conversion core and establish its maximum and minimum span.        他们的最大最小值是如何确定的，和REF电压之间有什么样的关系？在图表19 20 21三张图中，找不到他们之间的关系.知道的朋友指教下

  • [AD9203]internal reference configuration

    Hello,

    The customer had designed their circuit same as Fig. 20 (internal reference set for a 1V span),

    but there are no output voltages on VREF(0.5V), REFTF(1.25V), REFBF(1.75V).

    I would appreciate if you have any idea that should be checked.

  • Standby for the AD9203

    For the AD9203, how long does the part require to enter and leave standby mode?

  • RE: AD9200_θJa

    Hi,

    The AD9200 is a legacy product released 20+yrs ago before we started routinely including package thermal characteristics. My best recommendation to approximate ThetaJA on the AD9200 would be to compare it to a newer product that shares similar Package…

  • 最爱放大器之-AD8138

    最爱放大器之-AD8138 by xxff622

          AD8138 -- 使用过的第一款ADI的运算放大器！

          应用：使用在 CMMB数字电视接收机中。

          用途：作为AD9203的单端转差分的输入buffer，把单端的低中频IQ信号变为差分。同时提供适合的直流偏置给AD9203。

          特点：320M的高带宽以及  5 nV/√Hz的噪声参数完全胜任此工作，同时具有Vcom引脚，方便的设置共模电压。

  • RE: JESD stuck in reset w/ AD9208

    I think most of the confusion is that AD9203 J3 provides the global clock ( device clock in JESD204 terms) and AD7-V2 J3 provides the transceiver reference clock to the evaluation design.

    If you can somehow take the AD9208 J3 clock and connect it to…
