Abstract
A method and apparatus for generating reference voltages for a flat panel display system using a digital to analog converter (DAC) to supply multiple reference voltages to the flat panel display system. The DAC is adapted to accept digital input voltage reference from one of a plurality of registers and to provide an analog output to one of a plurality of sample and hold circuits. A controller selects which one of the plurality of registers is coupled to the DAC input, and selects which one of the plurality of sample and hold circuits is coupled to the DAC output.
