• AD9238 wrong output

    Hi folks,

    I'm facing issue with the AD9238 dual 12-bit ADC. The following settings I've used are:

    REFT_A and REFT_B short with recommend decoupling circuit

    REFB_A and REFB_B short with recommend decoupling circuit

    VREF = 1V

    SENSE = 3.3V

  • AD9238, AD9248 - Evalustion schematic Ad9238BCP-65EBZ

    We need some evaluation board with AD9238 which is suitable for DC (not only
    for AC). We know there are evaluation boards which allow only AC evaluation
    (e.g. AD9238BCP-65EBZ ).
    In contrast, other evaluation boards allow both DC and
    AC evaluation…

    something similar to the one shown below should work

  • AD9238及其他

    您好!

    我想问一下,AD9238这个芯片,1.它是否具有抗噪能力?2.它的外部时钟的对频率稳定程度有什么要求么?有的话这种要求频率稳定度在多少范围呢?

    3.除了这种AD芯片,您公司是否有AD采样率在几十KS/s~几十MS/s,且具有正弦外部时钟的芯片呢?

  • The question about the chip AD9238 and others

    Hello!

    I want to ask the question about  the chip AD9238, 1. Does it have anti-noise ability? 2. Is there any requirement for the frequency stability of its external clock? If so, what is the required frequency stability?

    3. In addition to this AD chip…

  • AD9238突然没有输出了

    AD9238之前用的好好的,但是这次重新制版后芯片没有任何输出了,配置信息如clk为8MHZ,pown和oeb都设置为低电平,这些都没有变化,跟以前一样,请问还有没有其它什么原因能够导致芯片没有输出?

  • AD9238 can't output

          Before, AD9238 was very good for use , but now the chip can't  output any digital signal.The difference between now and before is PCB board ,then  other configuration parameters have not be changed, such as CLK 8MHZ(clk-input)、 Pown and OEB( are be set…
