PROBLEM TO BE SOLVED: To obtain a PWM output circuit for converting a PWM signal into an analog voltage in which the output potential is fixed to a desired level at the time of standby and current consumption is suppressed. SOLUTION: The PWM output circuit comprises a means for fixing the input of the PWM output circuit to a reference potential or releasing the input at the time of standby, and a means for connecting the output to the reference potential through a resistor. The output is fixed to a desired potential by selecting the resistance of the resistor connected to the reference potential appropriately. Since power of the circuit is reduced except the resistor connected with the reference potential and the output, current consumption is reduced. COPYRIGHT: (C)2005,JPO&NCIPI
