Abstract
A touch screen digitizing system comprising a touch screen unit and an analog to digital converter. The touch screen unit includes a first resistive sheet with opposing first and second terminals and a second resistive sheet with opposing third and fourth terminals. The first and second resistive sheets are alternatively energized through the first, second, third, and fourth terminals. The analog to digital converter has an input coupled to the third terminal when the first resistive sheet is energized and the second resistive sheet is not, and coupled to the first terminal when the second resistive sheet is energized and the first resistive sheet is not, a first reference terminal dynamically coupled to a first reference voltage, a second reference terminal dynamically coupled to the second reference voltage, and an output terminal providing digital output data.
