Abstract
Provided is a control circuit that controls the amplitude by using a voltage regulator and that has improved accuracy in amplitude control. The control circuit includes a first voltage regulator and a second voltage regulator. The first voltage regulator in the control circuit generates one of a pair of voltages from a predetermined reference voltage and supplies the one of the pair of voltages to one of a power supply terminal and a ground terminal of a driver. In addition, the second voltage regulator generates the other of the pair of voltages from the one of the pair of voltages and supplies the other of the pair of voltages to the other of the power supply terminal and the ground terminal.
