ABSTRACT:
A digital to analog converter for converting alternately supplied first and second channel digital data words to first and second channel analog output signals comprises a current producing circuit for selectively producing currents corresponding to the digital data words, respectively; first and second channel voltage producing circuits for producing the first and second channel analog output signals in response to the currents from the current producing circuit; and a switch disposed between the current producing circuits and the first and second channel voltage producing circuits for selectively supplying the current corresponding to the first channel digital data word to the first channel voltage producing circuit and the current corresponding to the second channel digital data word to the second channel voltage producing circuit.
