Title:

レーザダイオード駆動回路

Document Type and Number:

Japanese Patent JP4799011

Kind Code:

B2

Abstract:

A circuit for driving a semiconductor laser including a semiconductor integrated circuit, which controls the drive of the semiconductor laser, and is connected to one end of the semiconductor laser. Moreover, the driving circuit incorporates a first power source +Vcc that supplies by way of the semiconductor integrated circuit a drive voltage to one end of the semiconductor laser and a second power source −Vcc, which is connected to the other end of the semiconductor laser and supplies a drive voltage to the other end. Furthermore, the drive circuit incorporates a voltage clamp circuit, connected to a connection terminal connecting the semiconductor laser and the semiconductor integrated circuit, for adjusting the electric potential of the connection terminal.
