Abstract
A driving circuit includes channels, a positive converting unit, a negative converting unit, an input switch, and an operational amplifier. A first digital data and a second digital data are alternatively transmitted in a first channel and a second channel. The positive converting unit and negative converting unit are respectively disposed in first channel and second channel and convert first digital data and second digital data into a positive analog data and a negative analog data. A first input terminal and a second input terminal of operational amplifier are respectively in first channel and second channel. After input switch respectively transmits positive analog data and negative analog data to first input terminal and second input terminal or to second input terminal and first input terminal, positive analog data and negative analog data are transmitted in a channel of the channels corresponding to entering operational amplifier.
