Abstract
A signal transmitting apparatus that may suppress generation of a noise voltage attributable to a common mode voltage is provided. A transistor Pis connected between a first terminal of a sending coil and a power supply voltage. A transistor Nis connected between the first terminal and a ground voltage. A transistor Pis connected between a second terminal of the sending coil and the power supply voltage. A transistor Nis connected between the second terminal and the ground voltage. In a period-PEa coil current flowing in a positive direction is generated by turning on the transistors Pand Nand turning off the transistors Pand N, and then the transistor Nis turned on in response to turning off the transistor P. In a period PE, a coil current flowing in a negative direction is generated by turning off the transistors Pand Nand turning on the transistors Pand N, and then the transistor Nis turned on in response to turning off the transistor P
