Abstract
A first selector receives a second input signal and a second reference voltage, and selects either one. A first buffer receives the output signal of the first selector, and outputs the signal thus received to a terminal of the first resistor, and to a terminal of the third resistor. A second selector receives a first input signal and a third input signal, and selects either one. A fourth selector receives, as input signals, the output signal of an operational amplifier, a signal that corresponds to the output signal of the second selector, and a signal that corresponds to the second input signal, and selects one signal selected from among the signals thus received.
