PURPOSE:To prevent a jump during switching without producing any drift in an output by holding invariably constant impedance even when switching operation is performed. CONSTITUTION:The output of a comparator 27 is supplied to a changeover switch 29 directly and to a changeover switch 28 through an inverter 30. When a contact A of the changeover switch 28 is made, a contact D of the changeover switch 29 is made. Similarly, when a contact B is made, a contact C is made. Thus, when the output of a receiver 23 is connected to an output terminal 33, the output of a receiver 24 is connected to a load 32, and when the output of the receiver 24 is connected to the output terminal, on the other hand, the output of the receiver 23 is connected to the load 32. Thus, invariably constant loads are placed on the outputs of the receivers. |
