• AD7920 12-bit ADC lab

    I set up the AD7920 12-bit ADC lab but do not get the screens that are shown.  Here are my screens:

    layout:

    Why do I not get any output from the MISO logic analyzer ?

    Could the chip layout be backwards from the web layout, as the "1" and "8" in the…

  • AD7920无法读出转换结果

    电路使用AD7920,硬件如下图,处理器采用AT89S52,软件模拟时钟I信号,读出的数据不正确,且不固定.

  • AD7920不工作

    我用AD7920进行AD变换,给定电源电压为5V,使用FPGAAD进行SPI通信,下面是电路原理图

    但是实际测试中,给定模拟输出电压为2.5V(事实上无论给定电压是多少结果都一样)AD的输出一直是零。下面是FPGA输出的片选CS信号,和时钟信号,时钟信号频率为97KHz,采样频率为500Hz

    1 片选信号与时钟信号,3个周期


    2 片选信号与时钟信号,1个周期

    1 片选信号与输出信号,3个周期

    1 片选信号与输出信号,1个周期

  • RE: AC Current Measurement

    Hi

    For 12 Bits, single channel SAR, look at AD7920, the AD7910 is the 10 bit version of this part.

    If you need more channels then look at AD7912 (2 channel) AD7923/7 (4 channel/8 channel).

    For a 12 bit sigma delta look at the AD7170.

    These devices…

  • RE: Measurement of pulse amplitude - suggestion for ADC

    Hi Henning,

         We have some I2C ADC interface that may fit your application, you may check the AD799x. Just like to ask on when are going to use the trigger feature, is it when the pulse amplitude hit some kind of limit or outside the range? I am also…
