Abstract:
1. A driving circuit, comprising: a plurality of channels, comprising a first channel and a second channel, wherein a first digital data and a second digital data are alternatively transmitted in the first channel and the second channel; a positive converting unit, disposed in the first channel, for converting the first digital data into a positive analog data; a negative converting unit, disposed in the second channel, for converting the second digital data into a negative analog data; an input switch, coupled to the positive converting unit and the negative converting unit; and an operational amplifying module, coupled to the input switch, wherein a first input terminal and a second input terminal of the operational amplifying module are disposed in the first channel and the second channel respectively; wherein the input switch transmits the positive analog data and the negative analog data to the first input terminal and the second input terminal respectively or to the second input terminal and the first input terminal respectively accordingly to a switch control signal, the positive analog data and the negative analog data are transmitted in a channel of the plurality of channels corresponding to entering the operational amplifying module.
