ABSTRACT:
A digital to analog converter is described for a multimedia system in which the magnitude of the analog output is controlled by signals applied to level select inputs of the digital to analog converter. Digital signals to be converted to an analog output are connected to a different set of inputs. This converter is advantageous for use in a display system where the brightness of the display may be independently controlled by the signals applied to the level select inputs. In this way, the digital information signals to be converted to an analog signal need not be modified to increase or decrease the brightness of the display.
