ABSTRACT:
Provided is a signal generating apparatus that outputs from an output end thereof an output voltage corresponding to input data supplied thereto, comprising: a DA converter that outputs a voltage corresponding to data supplied thereto; a capacitor section that is provided between the output end and a standard potential; a transmission switch that provides a connection or a disconnect between a voltage generating end of the DA converter and the output end; and a control section that causes the DA converter to charge the capacitor section with a voltage corresponding to the input data by repeatedly connecting and disconnecting the transmission switch, thereby causing the voltage of the capacitor section to gradually approach the output voltage corresponding to the input data.
