ABSTRACT:
An analog insulation multiplexer not causing magnetic saturation even if a small transformer is used and having a wide use temperature range. The analog insulation multiplexer includes: a first switching element for generating a drive control signal in accordance with an external signal; a drive insulation transformer for receiving the drive control signal on a primary side via a first resistor and for delivering an insulated drive control signal from a secondary side; a second switching element for chopping an analog signal input in accordance with the insulated drive control signal; and an analog signal insulation transformer for delivering an insulated chopped analog signal on a secondary side. The analog insulation multiplexer further includes a secondary side output adjusting circuit having a second resistor connected, on the primary side of the drive insulation transformer, in parallel to the first resistor and a capacitor having one end connected to a ground and another end connected in series to the second resistor.
