使用AD7472时，模拟输入电平最大达到5V，怎么接入AD7472，如果用运放，我只有一个单电源，怎么接

hello guys, Im new here. i hope u can help me how to write coding in c using avr microcontroller to control the external ad7472 conversion, my supervisor ask me to do that. the problem is i dont know how to control the cnvst because i never used avr.…

The Data sheet for AD7470/AD7472 says acquisition time is *minimum* 135[ns]  in "Specification" section and then in the "Timing Specfications" section says this number is a max. I assume this is an error or am I missing something?

Hello guys, I'm currently working on AD7472. according to the datasheet the REF IN is 2.5V which means the VIN can only varies from 0 to 2.5V. But i want to change the REF IN FROM 2.5V to 5V so that the ADC can read the VIN from 0 to 5V. How do u guys…

关于AD选型过程中，看到ADI出了一些针对直接射频采样的高速宽带ADC和DAC，比如AD9625和AD9144，最大采样率可以支持2.5GSPS和2.8GSPS.
我一直有个观点，就是SDR的一个目标是AD/DA尽可能的去靠近天线，这两款芯片组合起来可以对 GHz频段信号进行直接射频采样和直接射频合成。以前我也一直觉得，要想对更高频率进行AD转换，就需要更高采样率的ADC，可我最近研究了带通采样（欠采样）定理后，采样速率只要满足带通采样速率的要求就可以 了，这样的话，ADC的采样速率只和接收信号的带宽有关系…
