本例使用某个前例(参考文献1)中的电路作为输入。IC1和IC3为ADG5213四开关,有独立的逻辑电平控制输入端(图1与参考文献2)。在输入为高时,开关S2和S3打开,开关S1和S4闭合。当各个开关的控制输入端为低时,它们分别转换到相反的状态。电路现在处于 This example uses the circuit in one of the previous cases (Reference 1) as input. IC1 and IC3 are four switches of the ADG5213 with independent logic level control inputs (Figure 1 and Reference 2). When input is high, switches S2 and S3 are open and switches S1 and S4 are closed. When the control inputs of the individual switches are low, they switch to the opposite states respectively. The circuit is now
