  • EVAL-AD7980-PMDZ Interfaced with Artix-7 FPGA using SPI

    I'm trying to interface basys 3 FPGA board to EVAL-AD7980-PMDZ using SPI. 

    I was trying to understand example program from analog devices web-page for nexys 3

    Demo code is in https://wiki.analog.com/resources/fpga/xilinx/pmod/ad7980

    Please help me understand…

  • AD7980基准电压使用OPA170作为电压缓冲器ADC数据不成线性

       

    最近做一个项目时,如上图所示,REF_5V为REF5050输出,当AD7980在使用OPA170作为基准电压缓冲器时,其ADC值异常稳定,一个LSB都不跳;当输入信号变化大时,ADC结果几乎是以250个LSB的倍数跳动,很少出现10个LSB的跳动;但将OPA170更换为AD8066ARZ时,其转换结果在可接受范围内;请教一下这是因为什么原因影响的呢!

  • AD7980连接?

    如题,想请问一下能不能按照如下的方式接线。因为我板子上用磁珠将模拟地和数字地分隔开来了,所以用AD7980时,我就区分了模拟地AGND和数字地DGND。我将REF、VDD对应模拟地AGND,将IN-和GND引脚连接在一起,也对应模拟地AGND,而VIO作为数字电源,对应数字地DGND。
