Patent ID: 7339511

Claim:
A time division sampling digital to analog converter for driving a flat panel display, the converter comprising: timing signal generation means for generating timing signals that are used to provide operation timing signals for circuit components or to perform synchronization; data selection means for receiving n-bit digital data as an input, dividing the n-bit digital data into k groups, and outputting the divided digital input data in response to timing signals from the timing signal generator; k reference signal generation means for each outputting 2 n/k analog reference signals; reference signal selection means for receiving the outputs of the reference signal generation means as inputs, and outputting only 2 n/k analog reference signals selected according to a timing signal from the timing signal generation means; a multiplexer for outputting one of reference signals from the reference signal selection means using the n/k-bit digital data from the data selection means as a control input; and sampling mode analog addition means for sampling and storing the output of the multiplexer according to a timing signal from the timing signal generation means.
