Abstract
An interface circuit includes a receiver, a first terminal resistor, a second terminal resistor, a common mode capacitor, a first switch, a second switch, and a common mode potential adjustment circuit. The receiver includes a first channel for receiving a first channel voltage, and a second channel for receiving a second channel voltage. The common mode capacitor provides a common mode potential. The first switch electrically connects the first terminal resistor to the common mode capacitor, and the second switch electrically connects the second terminal resistor to the common mode capacitor. The common mode potential adjustment circuit is coupled to the first switch, the second switch and the common mode capacitor, and adjusts the common mode potential according to the first channel voltage and the second channel voltage.
