Abstract
A semiconductor device has a multiplicity of DAC channels for performing digital-to-analog conversion of video signals. Signal processing means for delaying processing of signals by a predetermined delay time is provided in at least one DAC channel. The signal processing means functions as a phase inversion means to reduce cross talks between the DAC channels. The signal processing means also functions as a delay circuit to reduce voltage fluctuations in the power supply.
