Time division sampling digital to analog converter for driving flat panel display, method of implementing the same, and data driver circuit using the same

Abstract

Disclosed herein are a time division sampling digital to analog converter for a flat panel display, a method of implementing the digital to analog converter, and a data driver circuit using the digital to analog converter. The time division sampling digital to analog converter includes a timing signal generation means for generating timing signals, a data selection means for receiving n-bit digital data, dividing the n-bit digital data into k groups, and outputting the divided digital input data; k reference signal generation means for each outputting 2n/k analog reference signals; a reference signal selection means for receiving the outputs of the reference signal generation means and outputting only 2n/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 a 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.
