Abstract
A selection section () selects a step voltage, among a plurality of step voltages (SV, SV, SV, . . . ) each having a voltage value changing stepwise, corresponding to the digital value of digital data (D-DATA). For each of the plurality of step voltages (SV, SV, SV, . . . ), different digital values are allocated to different steps of the step voltage. An amplifier section () amplifies the step voltage selected by the selection section (). An output section () outputs the step voltage amplified by the amplifier section () as an output voltage (Vout) for a time period corresponding to the digital value of the digital data (D-DATA).
