确定我曾尝试了max474双运算放大器和他们的工作真的很好，所以与那些装上而不是在ts922电阻值可以回去，以正本显示，在上述的示意图。
OK I have tried the MAX474 Dual op-amps and they work really well, so with those fitted instead of the TS922 the resistor values can go back to the originals as shown in the schematic above.
在模拟域，双位置控制器的主要部分是模拟比较器或开环运算放大器。
In the analog domain, the basis for the basic implementation of a two-position controller is an analog comparator or an open-loop operational amplifier.
