Analog to digital converter controller
First Claim
1. A touch screen controller for use with a touch screen device, the touch screen controller comprising:
- a set of inputs for receiving an interference signal from the touch screen device, the set of inputs also receiving analog data from the touch screen device; and
a converter operatively coupled with the set of inputs, the converter being capable of digitizing the analog data received from the touch screen device as a function of the interference signal.

Abstract
A touch screen controller has a converter that digitizes analog input as a function of an interference signal generated by an underlying touch screen device. To that end, the touch screen controller includes a set of inputs for receiving the noted interference signal from the touch screen device. The set of inputs also receives analog data from the touch screen device. The above noted converter, which is operatively coupled with the set of inputs, is capable of digitizing the analog data received from the touch screen device as a function of the interference signal.

9. A controller for controlling an analog-to-digital converter, the controller comprising:
-
an input for receiving an interference signal;
logic operatively coupled with the input, the logic producing a control signal that is a function of the interference signal; and
an output for forwarding the control signal to the analog-to-digital converter, the analog-to-digital converter digitizing analog signals as a function of the control signal. - View Dependent Claims (10, 11, 12, 13, 14)
