トランス絶縁形マルチプレクサ。A plurality of input signals are each supplied to the primary transformer winding of the isolation transformer via a changeover switch, and based on the supplied signals, a signal induced in the secondary transformer winding is amplified by an amplifier and sample-holded. In an isolated type multiplexer that outputs an output signal through a circuit and an analog-to-digital converter, the isolation transformer is supplied with the output signal of the sample-and-hold circuit and is turned off when the changeover switch for each input signal is turned on; A transformer-insulated multiplexer characterized by having a reset winding that turns on when the switch is off.
