In the figure is the dual polarity input voltage/current separation amplifier circuit of transformer coupling type. In the circuit, DC/DC converter is in the same pattern with the FET chopper, the circuit adopts the analog switch 4066 to replace FET as the chopper, 4066 is connected as a bridge circuit which separates the signals by the transformer T1, as the circuits on the primary stage are the same, therefore, it has the function of dual-way input. Besides, with the positive/passive power supply driving the analog switch 4066, the forward/backward signals can be processed in the power supply voltage range.
