Darlington tube
Darlington tube-
The system adopts double way and sampling feedback way of working to correct the output voltage ; with integrated op-amp and Darlington tube composition power amplification circuit ; using a keyboard control and synchronous serial port LED display .
系统采用双路D/A差分，A/D采样反馈的工作方式，对输出电压进行校正；用集成运放及达林顿管组成功率放大电路；利用键盘控制；及同步串行口的LED显示。
