<p><P>PROBLEM TO BE SOLVED: To provide a digital drive device in which instability of a circuit due to a local voltage drop is reduced. <P>SOLUTION: The digital drive device 10 includes a load digital circuit 27, a clock generation circuit 26, a power supply part 50, a clock control unit 30, and a temperature sensor 24. The clock generation circuit 26 supplies clocks of a predetermined speed to the digital load circuit 27. The clock control unit 30 controls a clock speed to be output from the clock generation circuit 26. In a clock setting table 25 included in the clock control unit 30, correspondence between a temperature detected by the temperature sensor 24 and the clock speed is recorded. When acquiring the temperature detected by the temperature sensor 24, the clock control unit 30 refers to the clock setting table 25 and instructs the clock generation circuit 26 to generate a clock speed corresponding to the acquired temperature. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
