    本方案选用ADI的DAC芯片AD7940，AD7940 是一款14位、快速、低功耗、逐次逼近型ADC，采用2.50 V至5.5 V 单电源供电，最高吞吐速率可达100 KSPS。该器件内置一个低噪声、宽带宽采样保持放大器，可处理7 MHz以上的输入频率。

    通过将波形的数据存储于FPGA内部ROM中，然后调用ROM中的数据，输出需要的波形。AD7940后面采用继电器和运放电路，产生电压、电流可变换输出。

    数字量信号输入首先经过光耦隔离后，经过比较器后输入至FPGA直接采集。

    光耦需选择高速…

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…
