ABSTRACT:
An improved output circuit for driving a loudspeaker with a single-polarity current source is disclosed. The output circuit comprises a digital to analog converter including a series circuit of a variable register and a field effect transistor for generating a variable bias potential, a plurality of current source transistors and a plurality of transfer field transistors each for selectively applying the variable bias potential to a gate of an associated current source transistor in accordance with a digital signal; a loudspeaker; and two pairs of switching transistors for alternately supplying the loudspeaker with different polarities of an output current of the digital to analog converter.
